An optimal lossless commutation quadratic PWM Boost converter

This paper presents a PWM boost power converter, where the DC voltage conversion ratio has a quadratic dependence on the duty cycle, providing a large voltage step up (from 24 V to 160 V). By introducing two resonant networks, soft switching is achieved, providing highly efficient operating conditions for a wide load range at high switching frequencies.
