| Abstract: | Nowadays it is popular to use digital control in power supply design.A PFC project based on average current control is presented. Hardware and software of the control system are analyzed.The simulation results of Matlab confirm that the circuit parameters are appropriate.A laboratory prototype based on TMS320LF2407A is presented.The test results validate a good performance of the digital implementation under the AC line voltage variation,with the switching frequency 50 kHz. |
