Switched Boost Inverter for Induction Motor Drive Application

Abstract

Switch Boost Inverter (SBI) is a single stage DC to AC power converter and it is derived from the Z - source inverter. SBI converter can possible to supply both DC and AC loads simultaneously from a single DC input source. The specialty of SBI is it can work either in buck or boost mode operations with a wide range of obtainable output voltages from a given input voltage, unlike the traditional buck-type voltage source inverter. The DC-AC inverters usually operate on  Pulse Width Modulation (PWM) method. PWM inverter is utilized to keep the output voltage of the inverter at the rated voltage independent of the output load. Here a single phase induction motor is driven by the inverter circuit. The output waveforms are taken in each step and analyzed.
