DIY Electronics Project: Building a Simple Power Inverter Using the PS11035

Description

The PS11035 is a high-voltage, high-speed insulated-gate bipolar transistor (IGBT) module, which is ideal for building power conversion circuits such as inverters, motor drives, and switching power supplies. IGBTs combine the fast switching properties of MOSFETs with the high-current and high-voltage handling capabilities of bipolar transistors, making them well-suited for high-efficiency power control in various applications. In this project, we will use the PS11035 IGBT module to build a simple power inverter that converts DC (direct current) into AC (alternating current). This inverter can be used in applications such as powering small appliances or electronics from a battery. Components Needed PS11035 IGBT Module – For handling high-voltage power conversion 12V DC Power Supply – The input to the inverter Transformers (12V to 120V) – To step up the voltage to AC mains level Oscillator Circuit (555 Timer IC) – To generate the switching signal for the IGBT Heat Sink – For cooling the PS11035 module Capacitors and Diodes – For filtering and protection Breadboard and Jumper Wires – For building the circuit Load (Small AC Appliance) – To test the inverter Understanding the PS11035 The PS11035 IGBT module is a high-power component that can handle up to 600V and currents of around 25A. It is designed for switching applications, allowing it to efficiently handle the conversion of DC to AC. This component is commonly used in motor control circuits, inverters, and other high-voltage applications. In this project, we will use the PS11035 to build a basic inverter circuit, where a low-voltage DC supply (12V) is converted to a high-voltage AC output suitable for powering small appliances or electronic devices. Step-by-Step Instructions 1. Set Up the Oscillator Circuit To control the switching of the PS11035 IGBT, we need an oscillating signal. This can be generated using a simple 555 Timer IC configured in astable mode. The 555 timer will produce a square wave signal that alternates between high and low states, which will control the on-off switching of the IGBT module. Connect the 555 Timer on the breadboard, and configure it in astable mode with appropriate resistors and capacitors to set the frequency. For this project, a frequency of 50Hz is suitable for generating a typical AC output. Connect the output of the 555 timer to the gate of the PS11035 module. 2. Connect the PS11035 IGBT Module Place the PS11035 IGBT module on the breadboard and connect its emitter to the ground of the circuit. Connect the collector to the primary winding of a step-up transformer (12V to 120V transformer) to generate the AC voltage from the DC input. The output from the 555 timer will control the gate of the IGBT, turning it on and off at a high speed to simulate an AC waveform on the primary side of the transformer. The transformer will then step up the voltage to the desired AC output level. 3. Add the Transformer A 12V to 120V transformer is needed to step up the low-voltage DC input to a higher-voltage AC output. Connect the primary side of the transformer to the collector of the IGBT, as mentioned earlier. The secondary side of the transformer will output 120V AC, which can then be used to power small appliances. 4. Power the Circuit Connect the 12V DC power supply to the circuit. The positive terminal of the power supply should be connected to the other side of the primary winding of the transformer, while the negative terminal should be connected to the ground. The 555 timer will begin oscillating, switching the IGBT module on and off, which in turn will create the alternating current necessary to power the transformer. 5. Test the Inverter Once the circuit is assembled, power it up and measure the output voltage from the transformer using a multimeter. You should see an AC voltage of approximately 120V (depending on your transformer’s ratio). You can now connect a small load, such as a light bulb or a small fan, to test the inverter's functionality. 6. Add Heat Management The PS11035 IGBT module will generate heat during operation, especially at higher loads. Attach a heat sink to the module to ensure that it remains cool and operates efficiently. Proper heat management is essential in high-power circuits to prevent damage to the components.

Conclusion This simple power inverter using the PS11035 IGBT module demonstrates the power and efficiency of using IGBTs in high-voltage switching applications. With this project, you can convert a 12V DC supply into a usable AC output for small appliances, opening the door to more advanced power conversion projects. The PS11035's high-voltage handling capabilities make it an excellent choice for DIY inverters and other high-power applications. From Utsource
