This document discusses a 3-phase PWM inverter. It begins by defining an inverter as an electronic device that converts DC to AC. It then explains that PWM inverters use pulse width modulation technology to control the width of switching pulses and thereby regulate the output AC voltage. The document presents the block diagram of a 3-phase PWM inverter and describes how PWM signals are generated for each phase. It notes that 3-phase PWM inverters are used in applications like solar panels, motor speed control, and HVDC power transmission.

- 2. INVERTER • A inverter or power Inverter is an electronic device or circuitry that changes direct current (DC) to alternating current (AC).
- 3. Pulse Width Modulation Tech. • The AC voltage output depend on the width of the switching pulse. • The inverters based on PWM technology are superior in many factors compared to other inverters designed using conventional technologies.
- 4. Why PWM is used?. • PWM inverter output voltage of the inverter at the rated voltage(220V AC) (depending on the country) irrespective of the output load. • The inverters based on PWM technology has a lot of protection and control circuits compared to the traditional inverters.
