This report focuses on the design, construction, and testing of a PWM inverter capable of converting 1.5 kW. The purpose for the inverter is to convert DC solar energy to power an air conditioner. The inverter uses a bipolar control scheme which comes from a PIC microcontroller. This report contains the advantages and disadvantages of all the PWM control schemes. Furthermore, the testing shows bipolar inverter characteristics and a sample use of filters to obtain sinusoidal waveforms. The design of the circuit makes the inverter easy and safe to use and test.
