Abstract
In some examples, a device includes a gate driver circuit and a control circuit configured to generate a first signal and a second signal, a duty cycle of the first signal encoding an amplitude of an electrical current having a sinusoidal shape, and a duty cycle of the second signal encoding a phase angle of the electrical current. The control circuit is configured to deliver the first and second signals to the gate driver circuit, which is configured to determine a duty cycle of a driver signal as a function of the first signal and of the second signal. The gate driver circuit is also configured to deliver the driver signal to a switch to cause the electrical current having the sinusoidal shape to be delivered to an electrical load.
