What is the difference between MOSFET based power Inverters vs. other Inverters?
The Inverter usually comprises of a power circuit which is ‘switched’ at a pre-determined Frequency to generate a stepped wave. There are various types of devices used in the inverter power circuit. Earlier technologies used bipolar junction transistors or BJT’s (1960’s) and power transistor (1970s). The latest generation devices are power MOSFET’s which have revolutionized the inverter technology and offer unique advantages over conventional devices. MOSFET’s are majority carrier, voltage-driven devices and their construction and principles of operation are fundamentally different from BJT’s, which are minority carrier, current-driven devices.
