Power conversion applications consist of an AC-to-DC conversion stage immediately following the AC source. The DC output obtained after rectification is subsequently used for further stages. Current pulses with high peak amplitude are drawn from a rectified voltage source with sine wave input and capacitive filtering. Increasing demands for higher power density, smaller size, more portability and more flexible systems spur industry to continuously design new generations of AC-DC power supplies using power devices with the lowest switching and conduction losses to increase efficiency, reduce thermal problems and improve power density.
