TAILIEUCHUNG - 800VA Pure Sine Wave Inverter’s Reference Design

This application note describes the design principles and the circuit operation of the 800VA pure Sine Wave Inverter. The pure Sine Wave inverter has various applications because of its key advantages such as operation with very low harmonic distortion and clean power like utility-supplied electricity, reduction in audible and electrical noise in Fans, fluorescent lights and so on, faster, quieter and cooler running of Inductive loads like microwaves and motors. | Jtffl Texas Instruments Application Report SLAA602 - June 2013 800VA Pure Sine Wave Inverter s Reference Design Sanjay Dixit Ambreesh Tripathi Vikas Chola High Performance Isolated Power ABSTRACT This application note describes the design principles and the circuit operation of the 800VA pure Sine Wave Inverter.
