Abstract :
A family of single-switch ZVS-CV (zero voltage switching and clamped voltage) DC/DC power converters, i.e., buck, boost, buck/boost, Cuk, Zeta, and Sepic, are presented. Each power converter is realized by employing a commutation inductor circuit which is connected in parallel with either a transistor or a freewheeling diode in a conventional PWM power converter. The steady-state characteristics of these converters are analyzed, including the voltage conversion ratio, the ZVS condition and the input and output current ripple characteristics. These analytical results are confirmed by experiments. The proposed technique is quite simple and output voltage control is easy
