| Abstract: | The full digital system employs voltage closed-loop control,and the regulater uses parameter-varying digital PI calculation,realizing complicate calculation not inherent in analog system and convenient phase-shifted control.Experiments are carried out on a 2 kW sampling machine with switching frequency being 2 kHz.Experimental results indicate that the design is reasonable,zero-voltage-switch control is achieved,and that the problem of oscillations with bridge rectifier is well resolved.The system can work as a middle-level-power DC-DC converter. |
