Pulse Width Modulated (PWM) DrivesAC Drives Using PWM TechniquesPower Conversion UnitThe block diagram below shows the power conversion unit inPulse Width Modulated (PWM) Drives . In this type of drive, adiode bridge rectifier provides the intermediate DC circuitvoltage. In the intermediate DC circuit, the DC voltage is filteredin a LC low-pass filter. Output frequency and voltage iscontrolled electronically by controlling the Width of the pulses ofvoltage to the , these techniques require switching the inverterpower devices (transistors or IGBTs) on and off many times inorder to generate the proper RMS voltage GeneratorThis switching scheme requires a more complex regulator thanthe Variable Voltage Input (VVI). With the use of amicroprocessor, these complex regulator functions areeffectively handled.
