| Abstract: | Presents voltage-source PWM rectifier for the design of electronic power load. The DSP device, TMS320F240 is used in the control system, which is a ideal choice of real time control in power converters. When the electronic power load is connected to utility power system, required performance is obtained: unit power factor, voltage and current harmonic components which meet IEEE-519 standard. The experimental results verify that some questions in some applications such as DC power source performance test are well solved. |
