Patent attributes
An electronic device is described. The electronic device includes line voltage measuring circuitry configured to measure a line voltage to produce a line voltage measurement. The electronic device also includes load voltage measuring circuitry configured to measure a load voltage to produce a load voltage measurement. The electronic device further includes a processor coupled to the line voltage measuring circuitry and the load voltage measuring circuitry. The processor is configured to adjust a voltage ramp waveform for a transition of a first metal-oxide-semiconductor field-effect transistor (MOSFET) and a second MOSFET based on the line voltage measurement and the load voltage measurement to minimize heat generation and electromagnetic interference creation by the MOSFETs. The first MOSFET and the second MOSFET control a current to a load in an alternating current configuration.
