  • Phase controller apparatus and methods
    Patent number: 10356859
    Abstract: A phase controller includes a plurality of pulse width modulation (PWM) circuits, a plurality of switching devices, a computing unit, and a latency generator. The plurality of PWM circuits output pulse signals. The plurality of switching devices are coupled to the respective plurality of PWM circuits, and switch on and off based on the pulse signals. The computing unit calculates the pulse signals to be output from the plurality of PWM circuits, based on outputs of the plurality of switching devices. The latency generator generates latency in any of the pulse signals so that edge positions of the pulse signals output from the plurality of PWM circuits do not collide with each other, wherein the pulse signals change values at the edge positions.
    Type: Grant
