This paper proposes a new resonant gate driver circuit for a soft switching synchronous buck converter in a fixed load condition. The switching energy can be fully recovered during current commutation phase in the gate driver while the diode conduction losses in the low and high side switches can be substantially reduced by employing additional L and C(More)
high output power density VHF converter has become important in recent years. This output power density of the converter is experiencing an adverse effect resulted from the applied switching frequency. In addition, the frequency which is higher than 20 MHz will no longer be applicable on the discreet SMT technology hence lowers the output power density.(More)
—This work is about the analysis of dead time variation on switching losses in a Zero Voltage Switching (ZVS) synchronous buck converter (SBC) circuit. In high frequency converter circuits, switching losses are commonly linked with high and low side switches of SBC circuit. They are activated externally by the gate driver circuit. The duty ratio, dead time(More)
(RGD) circuits operating in very high frequency (VHF) switching is discussed. The specific RGD circuits are normally applied only for certain applications due to their design limitations and drawbacks. The isolation techniques must be considered to avoid mismatch and interruption of signals as well as the dead time delay, size of components and choice of(More)
