ABSTRACT:
An avionics power conversion circuit having a first input adapted to receive an AC input signal, a second input adapted to receive a DC input signal and an output at which converted signals are provided. Power conversion circuitry, coupled to each of the first and second inputs and to the output, provides boost conversion of the AC input signal when the AC input signal is applied to the first input and provides flyback conversion of the DC input signal when the DC input signal is applied to the second input. The power conversion circuitry provides the boost conversion and the flyback conversion using a single transformer coupled between the first and second inputs and the output.
