DC 12V to AC 220V 150W Mini Inverter Module Price in Bangladesh

The DC 12V to AC 220V 150W Mini Inverter Module is a compact power conversion board designed to increase a low-voltage DC supply to a much higher-voltage output. It is commonly used in electronics experiments, DIY inverter projects, battery-powered prototypes, and applications that require a high-voltage output from a 12V DC source.

An inverter module is useful when a project needs to convert electrical energy from a battery or DC power supply into an alternative output form. This module uses a switching circuit and transformer-based voltage conversion to generate a high-voltage output from a 12V input.

Depending on the exact version, the board may provide selectable output voltage connections such as 110V, 200V, 220V, and 280V. Some versions also provide a separate high-voltage DC output after the conversion stage. The output selection and terminal arrangement must be checked against the markings on the actual PCB.

The module is generally advertised with a 150W output rating. However, its real usable output depends on the input power supply, cooling, wiring, load characteristics, and operating conditions. A 12V source supplying 150W of output power must provide considerably more than 12.5A once conversion losses are included.

An important distinction is that common versions of this compact board generate high-frequency square-wave output, often around 20–37kHz. This is not the same as standard 220V, 50Hz household AC. It is therefore not a universal replacement for a conventional mains inverter and is unsuitable for many household appliances.

For electronics enthusiasts, students, and engineers, this module provides a compact platform for studying DC-to-AC conversion, transformer operation, switching circuits, and high-voltage power electronics.

What Is a DC-to-AC Inverter?

A DC-to-AC inverter is an electronic circuit that converts direct current (DC) into an alternating or alternating-like electrical output.

Batteries and most DC power supplies provide direct current, where the current flows in one direction. Many traditional AC-powered devices are designed to operate using alternating current, where the voltage changes polarity periodically.

An inverter uses electronic switching components to control current flow and generate an output waveform. A transformer or other voltage-conversion stage can then increase the output voltage.

Different inverter designs produce different waveforms:

• Square-wave inverter: Produces a square-shaped output waveform.
• Modified sine-wave inverter: Produces a stepped approximation of a sine wave.
• Pure sine-wave inverter: Produces an output waveform close to conventional utility electricity.

The common 150W mini inverter board described here uses high-frequency square-wave conversion. Its output should not be confused with a conventional 220V, 50Hz household supply.

Key Features of the DC 12V to AC 220V 150W Mini Inverter Module

1. 12V DC Input

The module is designed for a nominal 12V DC input, making it suitable for compatible 12V battery systems and laboratory DC power supplies.

A stable input supply with sufficient current capacity is essential. At higher output loads, the module can draw substantial current from the 12V source. An undersized power supply or thin connecting wire may cause voltage drop, overheating, or circuit failure.

Always check the input voltage range specified for the exact board version before connecting it.

2. High-Voltage Output

The main purpose of the module is to step up a low-voltage DC input to a high-voltage output.

Common board versions provide selectable output connections marked for approximately 110V, 200V, 220V, and 280V. These options are generally selected through PCB terminals or jumper arrangements.

The available output voltage depends on the specific terminal combination and the module design. It may also change with input voltage and connected load because many versions do not provide regulated output.

3. 150W Rated Power

The module is advertised with a 150W output power rating, making it suitable for selected low-power applications and electronics experiments.

The 150W rating should not be interpreted as a guarantee of continuous operation at that power under every condition. Thermal performance, input supply capacity, load type, and ventilation all affect the achievable output.

For sustained operation near the rated power, adequate cooling is important. Some common versions recommend additional fan cooling when operating above approximately 100W.

4. Compact PCB Design

The compact circuit-board construction makes the module convenient for experimental electronics, custom power conversion projects, and embedded power systems.

Its small form factor can help reduce the space required for a prototype compared with a complete enclosed inverter. However, the exposed high-voltage terminals require a properly designed protective enclosure before the module is incorporated into a finished product.

5. Screw-Terminal Connections

Many versions use screw terminals for the DC input and output connections. This makes wiring and installation convenient without requiring every connection to be soldered directly to the board.

Terminal assignments and output markings can vary. Always follow the PCB labels and the documentation supplied with the exact version.

6. High-Frequency Switching Operation

Common versions use a switching controller and power MOSFETs to drive the transformer stage. Depending on the production batch, controller and MOSFET part numbers may differ.

The high-frequency switching design allows the board to provide a compact voltage-conversion solution. However, it also means the output is not equivalent to conventional 50Hz household electricity.

Technical Specifications

Specifications are representative of commonly sold 150W mini inverter boards, not a universal specification for every production version. Confirm the actual PCB markings and supplier documentation before connecting a load.

Working Principle

The module operates through a switching-based voltage conversion process.

First, a 12V DC supply is connected to the input terminals. The switching circuit controls the power MOSFETs, causing current to flow through the transformer primary winding in a controlled switching pattern.

The transformer increases the voltage to a much higher level. Depending on the design, the output is made available through different transformer winding connections or output terminals.

The general conversion process can be understood in four stages:

1. DC input: The module receives electrical power from a 12V DC battery or suitable power supply.
2. Electronic switching: The controller drives the switching MOSFETs to generate a high-frequency alternating signal.
3. Voltage transformation: The transformer increases the voltage from the low-voltage input side to the high-voltage output side.
4. Output delivery: The converted high-voltage output is made available at the designated terminals.

The output waveform and frequency depend on the circuit design. On common versions, the output is a high-frequency square wave rather than a standard 50Hz sine wave.

2. Not Suitable for Conventional Motors and Fans

Avoid connecting AC motors, fans, pumps, iron-core transformers, and other inductive loads to the high-frequency output unless the manufacturer explicitly confirms compatibility.

3. High-Voltage Electric Shock Risk

The output can cause serious injury or death. Never touch exposed output terminals or wiring while the module is powered. Use an appropriate insulated enclosure and professional high-voltage precautions.

4. High Input Current

At 150W output, the input current from a 12V source can exceed 12.5A because conversion is not 100% efficient. Use a suitably rated power supply, short and adequately sized wires, and appropriate input protection.

5. Cooling Requirements

The switching components can become hot during operation. Provide adequate ventilation and additional cooling where required by the specific board.

6. Limited Protection on Common Versions

Some commonly sold boards do not include comprehensive overload, short-circuit, reverse-polarity, or thermal protection. Do not assume these protections are present. External protection and careful system design are essential.

7. Measurement Difficulties

A standard multimeter may provide misleading voltage readings when measuring high-frequency square-wave output. Use suitable measurement equipment rated for the voltage and frequency involved.

Installation and Usage Tips

1. Check the input voltage requirements and terminal markings of the exact module version.
2. Use a regulated or otherwise suitable 12V DC supply capable of delivering the required current.
3. Install an appropriately rated external fuse close to the positive input source.
4. Confirm input polarity before applying power.
5. Select the correct output terminal configuration according to the PCB markings and documentation.
6. Keep the high-voltage output terminals insulated and inaccessible during operation.
7. Provide adequate ventilation and cooling, especially at higher output loads.
8. Begin testing with a suitable low-power compatible load.
9. Never overload or short-circuit the output.
10. Disconnect the DC supply before changing wiring or output connections, and verify that stored energy has been safely discharged.
