Review of Some Special Pulse Width Modulation Techniques: for power converters

Various forms of energy are needed in business and social life. The conversion and transformation of electrical energy obtained from both renewable energy sources and fossil sources may be required. Direct Current to Direct Current (DC-DC) Converter circuits or Direct Current to Alternating Current (DC-AC) inverters are used in these conversions. These circuits have power switches such as MOSFET, IGBT, and GTO to provide electrical energy to the load. Signals generated by Pulse Width Modulation (PWM) techniques are used to control these power switches. Some special PWM techniques will be examined in this book. First, square PWM and Linear PWM (LPWM) are examined. Square PWM generation technique and DC-DC converter application are made and its effect on the circuit and load are examined. Secondly, the Step Sinus Pulse Width Modulation (SSPWM) technique is reviewed. SSPWM technique is produced and inverter circuit simulation applications are made on various loads. Finally, the generation of Fractional Sine Pulse Width Modulation (FSPWM) and inverter application on different loads are done.
