摘要:This paper presents, a design of Programmable AC-DC Converter Using Pulse Width Modulation (PWM) Techniques in MATLAB with an impression of the well known voltage and current converter topologies used to realize a three-phase PWM AC/DC converter scheme. Preliminary from the voltage source inverter and the current source rectifier, the fundamentals of space vector modulation are summarized. The process of the AC/DC converter in different dynamic states powerfully depends on the modulation method applied. The power of the discussed modulation methods on the line current distortion and the switching frequency has been inspected. This technique depends on off line calculations of the pulses width for the first quarter cycle and stores these into a table. The residual pulses, for total cycle, are generated by using the values of the first quarter since there are conditions of quarter and half – wave regularity. Results show an important saving of microcontroller time and memory.
