Over modulation with Square wave PWM

Over-modulation means taking m beyond 1. pwm voltage source inverter is discuss here with examples. Over modulation transfers inverter operation from square wave PWM to ordinary square-wave control. Case 1: Single-phase bipolar square-wave PWM Vo waveform with over-modulation of single-phase bipolar PWM Ideal over-modulation makes a smooth transition from square-wave PWM to square-wave VSI but, …

Voltage Source Inverter operation

Voltage Source Inverter Square wave PWM

Voltage Source Inverter operation are discussed here with sketches and examples. In first stated before and this PWM is special also because it does not suppress lower-order harmonics in output voltage, which is contrary to the general expectations from a PWM inverter. Single phase Square wave PWM VSI Single-phase Square-wave PWM VSI has two implementation …

Voltage source Inverter Square-wave

Square-wave Voltage source Inverter Voltage source Inverter type Square-wave produces a square-wave-AC voltage output. We never attempt to filter this voltage, only those loads compatible with square-wave voltage can use it. E.g.       Lighting loads, Heating loads, AC motors (for high speed running) Single-phase square-wave Voltage source Inverter Circuit of single-phase square-wave VSI 𝑄1  to …
