WebAug 13, 2024 · 1 Normally you choose the switching frequency first, and select a device that matches your requirements at that frequency. For example, having suggested 250kHz, take the datasheet for that part and calculate its efficiency at that frequency. Does it meet your requirements? – user_1818839 Aug 13, 2024 at 17:18 1 WebThe process of converting DC voltage into AC voltage in the inverter section of VFD is called Pulse Width Modulation (PWM). Pulse width modulation uses transistors that on and off the DC voltage in a sequence to produce the desired AC output voltage and frequency. IGBTs (Insulated Gate Bipolar Transistor) are used as a transistor in VFD.
