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