Class E zero-current-switching rectifier with a series inductor

An analysis of a class-E zero-current-switching (low di/dt) rectifier is presented. The circuit consists of a rectifier diode, an inductor connected in series with the diode, and a filter capacitor. The addition of the series inductor allows the rectifier to decouple the diode on-duty cycle and the output voltage ripple. The series inductor sets the value of the diode on-duty cycle, which can be large, e.g. 0.5. The filter capacitor independently sets the level of the ripple. The diode turns on at zero di/dt and low dv/dt and turns off at low mod dt/dt mod , reducing switching losses, switching noise, and reverse-recovery current.
