Time-domain analysis of half-wave zero-current switch quasi-resonant converters by using SPICE

A SPICE-compatible time-domain equivalent circuit model of half-wave zero-current switch (HW-ZCS), based upon which half-wave zero-current-switch quasi-resonant converters (HW-ZCS-QRCs) can be analyzed by using SPICE, is proposed. As an example, the open-loop time-domain behavior of a buck (HW-ZCS-Q...

Zusammenfassung:A SPICE-compatible time-domain equivalent circuit model of half-wave zero-current switch (HW-ZCS), based upon which half-wave zero-current-switch quasi-resonant converters (HW-ZCS-QRCs) can be analyzed by using SPICE, is proposed. As an example, the open-loop time-domain behavior of a buck (HW-ZCS-QRC) can be analyzed without any simplifying assumptions by using SPICE to illustrate the applications of the equivalent circuit model proposed.< >
