| Abstract |
A 2.5kW, 50kHz digitally controlled Zero-Voltage-Switched Fullbridge Converter (ZVS-FBC) is presented. The features and difficulties of producing a digital controller operating at 100kHz are discussed. The controller is to implement sampling and calculation at
this frequency in order to effect true half-cycle control of the converter. A digital signal processor-based solution is presented and the Ziegler-Nichols technique is used to produce a
conservatively-designed control loop to test the feasibility of digital control at this frequency. |
