150W DC 12V to AC 110V/220V Inverter Boost Module

The 150W DC 12V to AC 110V/220V Inverter Boost Module is a compact high-frequency inverter board designed to convert 12V DC input power into high-voltage AC output. It is suitable for DIY inverter projects, vehicle power applications, backup-power experiments, and electronic projects requiring a high-voltage AC source from a 12V battery or power supply.

The module supports multiple output voltage tapping options, including approximately 110V, 172V, 200V, and 220V, allowing users to select a suitable output according to their application. It uses a high-frequency square-wave output at approximately 20kHz and is designed for applications where a simple high-voltage AC conversion stage is required.

With a compact 58 × 58 × 28mm form factor and a weight of approximately 120g, the module is easy to integrate into DIY electronic systems. It is primarily intended as an inverter boost stage rather than a complete consumer-grade AC power inverter.

Design and Construction

The module uses a compact PCB-based high-frequency inverter design for converting low-voltage DC power into high-voltage AC. Its small size makes it suitable for integration into DIY electronic enclosures and battery-powered systems.

The board provides multiple output terminals that can be used to obtain different voltage levels. This multi-tap arrangement allows the user to select a lower output voltage for suitable low-power electronic loads or a higher output voltage when required by the application.

For applications involving continuous or heavier loads, additional cooling such as a suitable heat sink is recommended. Adequate ventilation and appropriately rated wiring are also important for reliable operation.

Working Principle

The module takes 12V DC from a suitable power source and uses high-frequency switching circuitry to convert the DC input into a high-frequency alternating waveform. The onboard transformer then boosts the voltage to the required high-voltage AC level.

The output is a high-frequency square wave, rather than a utility-style pure sine wave. The available output voltage depends on which output terminals are selected.

The module is therefore best suited as an inverter boost stage for electronic projects rather than as a universal replacement for mains electricity.

Output Voltage Wiring

The available output voltage combinations are specified as follows:

Output Terminals	Approximate Voltage
V0 – V2	110V
V0 – V3	175V
V0 – V4	200V
V0 – V5	220V
V5 – V4	20V
V5 – V3	45V
V5 – V2	110V
V4 – V3	28V
V4 – V2	90V
V3 – V2	62V

Important: Output voltage values are approximate and can vary depending on input voltage, load, wiring, and operating conditions.

Applications

• DIY DC-to-AC inverter projects
• 12V battery inverter projects
• Vehicle power conversion experiments
• Car and truck electronics projects
• RV and boat power projects
• Emergency power experiments
• Electronic inverter-stage development
• High-voltage AC experiments
• Power electronics projects
• Educational electronics projects
• DIY backup-power systems
• Electronic prototyping
• Custom inverter development
• Night-market and portable power projects

Load Compatibility

Because the module produces a high-frequency square-wave AC output, it is not suitable for all types of AC appliances.

It should generally not be used directly with inductive loads such as:

• Motors
• Fans
• Coils
• Transformers not designed for the waveform/frequency
• Other loads requiring a sine-wave AC supply

For small electronic loads such as LED lights, mobile-phone chargers, or set-top boxes, selecting a suitable lower output voltage is recommended where appropriate.

Always verify the input requirements and waveform compatibility of the connected load before use.

Important Operating Guidelines

• Use only a suitable 12V DC power supply.
• Check the polarity carefully before connecting power.
• Do not reverse the power supply polarity.
• Use a power supply and wiring capable of supplying the required input current.
• Do not overload the module.
• Do not short-circuit the output.
• Provide adequate cooling for extended operation.
• An additional heat sink is recommended for heavier loads, particularly around 100W or more.
• Keep the module away from moisture and conductive materials.
• Do not touch the high-voltage output while powered.
• Disconnect the input power before changing output connections.

Output Measurement Note

Because the output is a high-frequency square-wave AC signal, measuring the no-load output voltage with a standard multimeter may produce an unusually high or inaccurate reading. The displayed value may not represent the actual effective output voltage.

Use an appropriate measurement instrument designed for the waveform and frequency when accurate measurements are required.

Special Application Note

Some switching power supplies use conventional rectifier components at their input. Connecting such equipment directly to a high-frequency AC output may cause excessive heating or damage to the rectifier section.

For electronic applications requiring DC input, an appropriate high-frequency-rated rectification and filtering stage may be required rather than directly connecting the equipment to the module’s AC output.

The suitability of any external rectifier, diode, capacitor, or filter must be determined according to the required voltage, current, frequency, and load characteristics.

Product Disclaimer

This is a high-voltage power-conversion module intended for experienced users and electronic DIY applications. The output can reach potentially hazardous voltage levels. Use appropriate insulation, enclosure, fusing, wiring, grounding, and electrical safety practices during installation and operation.

This module does not produce utility-grade pure sine-wave AC. Its high-frequency square-wave output may be unsuitable for many household appliances and inductive loads.

The stated 150W rating is application-dependent and requires an adequate 12V power source and appropriate thermal management. Actual output performance may vary according to input supply, load, cooling, wiring, and operating conditions.

Do not reverse the input polarity, overload the output, or short-circuit the module.

Once the module has been soldered or modified, it is not eligible for return according to the stated product conditions.

Product images are for representation only. The actual product may vary slightly in colour, PCB markings, component placement, dimensions, or overall appearance depending on the manufacturing batch.
