Web4 DC-AC Converter. The DC-AC Converter section of the High-Frequency Inverter is an H-Bridge, which converts the high voltage DC bus (380 V) into sinusoidal AC waveform. The sinusoidal PWM generation is done using the PWM interrupt handler in TMS320F28069 by entering into an infinite loop. Web2. Modeling and verification of dc/dc Boost Converter 2.1 Operation of dc/dc converter The dc/dc converter we address here is a switching converter. Specifically, the dc-dc converter is a power electronics circuit, which uses an inductor, a transformer, or a capacitor as an energy-storage element to convert electrical power from one voltage level
