This paper introduces a new dc-dc converter suitable for operation at very high frequencies (VHF) under on-off control. The converter power stage is based on a resonant inverter (the Φ2inverter) providing low switch voltage stress and fast settling time compared to other resonant topologies. A new multistage resonant gate driver suited for driving large, high-voltage RF Mosfet at VHF frequencies is also introduced. Experimental results are presented from a prototype dc-dc converter operating at 30 MHz at input voltages up to 200 V and power levels above 200 W under closed-loop control. These results demonstrate the high performance achievable with the proposed design.
