Abstract

This project portrays the design and construction of a pulse width modulation (PWM) inverter. The inverter is implemented as a unipolar converter. The inverter provides a steady single-phase sinusoidal 60Hz AC voltage output from a DC input. This is a basic DC-AC power converter that is built in 3 separate phases and integrated altogether at the end. The inverter can be broken down into the control unit, firing circuit, and the H-bridge. By using the PWM method, one can control the frequency and amplitude of the output by using a reference signal. This method will also avoid using a transformer because transformers have high power losses. This project will be dedicated to EE-410 power electronics students as an experiment to observe and experience the fundamental operations of a PWM inverter circuit at Cal Poly.
