Abstract:
A DC-DC voltage converter 40, which is adaptable to VHF operation, has a power oscillator 52 to which a filtered input DC voltage 50 is applied for conversion to an output DC voltage. The power oscillator includes a push-pull amplifier 58, 60 and an impedance transformation circuit 62 to which the amplifier is connected. The power oscillator also includes a rectifier circuit 64 which is connected to the impedance transformation circuit. A feedback circuit 68 controls the frequency of the oscillator to regulate the output DC voltage. The oscillator frequency depends on the impedance values of oscillator circuit components and the values of a plurality of oscillator component intrinsic parameters.
