Abstract
Modulation of switching intervals over a line cycle in an inverter system is provided. In one embodiment, an inverter circuit includes input and output ports, first and second switches. The inverter circuit provides a substantially sinusoidal output voltage or current. The first and second switches operate with a switching frequency and deadtimes. A first controller operates in conjunction with a first control loop to provide control signals for the first switch and second switch. A second controller operates in conjunction with a second control loop and adapted to provide a plurality of distinct timing parameters for a plurality of individual time periods within the line cycle of the substantially sinusoidal output voltage or current. The first controller is adapted to provide the control signals for the first switch and the second switch based in part on the timing parameters provided by the second controller.
