Operation at higher frequencies considerably reduces the size of passive components, such as transformers and filters. However, switching losses have been an obstacle to highfrequency operation. To reduce switching losses and allow high-frequency operation, Pulse Width Modulation (PWM) with soft-switching techniques have been developed. These techni...
