  • Patent number: 8330444
    Abstract: According to one configuration, a monitor circuit monitors a delivery of power supplied by one or more switch devices to a dynamic load. Based on an amount of power delivered to the load as measured by the monitor circuit, a control circuit produces a voltage control signal. A gate bias voltage generator circuit utilizes the voltage control signal to generate a switch activation voltage or bias voltage. A switch drive circuit uses the switch activation voltage as generated by the bias voltage generator to activate each of the one or more switch devices during a portion of a switching cycle when a respective switch device is in an ON state, and the respective switch device conducts current from a voltage source through the switch device to the load. The control circuit adjusts the voltage control signal to modify a level of the switch activation voltage depending on the dynamic load.
