| Technology: | Researchers at the Power Electronics Laboratory at University of California, Irvine, received a U.S. patent for a device that uses one cycle control for controlling DC-to-AC switching converters. This is achieved by forcing the average of a controlled switched variable to be exactly equal to the control reference in each switching cycle. Potential subharmonic oscillations in a switching power amplifier, which occurs in the DC-to-AC application of this method is prevented by adding an offset voltage to the averaged controlled switched variable. This is fed back and compared to a control reference, which compares and is then used to switch the switching power amplifier. Switching errors are corrected by resetting the integrator that averages the controlled switched variable and a time interval at least an order or magnitude less than the switching time of the switches in the switching power amplifier. |
