ABSTRACT:
A power converter device and method are provided. The power converter device includes an input power source and an input inductor configured for coupling a power of the input power source to the device. A switch is configured to regulate a power of the input power source through the input inductor. A shunting diode is coupled between the switch and the input inductor. A resonant load is coupled with the input inductor. A switching element is coupled with the input inductor and the resonant load and configured to operate at a fixed frequency. The power converter device also includes a control circuit for modulating a frequency of the switch and a driving module for driving the switching element at the fixed frequency. In an exemplary embodiment, the power converter device is a Class-E amplifier. The fixed frequency is a frequency equal to a resonant frequency of the resonant load. In one embodiment, the power converter device is configured as an integrated circuit device.
