Title:
SINEWAVE INVERTER USING HYBRID REGULATOR
Document Type and Number:
WIPO Patent Application WO2004084388
Kind Code:
A3
Abstract:
A sinewave inverter for converting unstable DC voltage from a variable source (10) such as batteries, fuel cells, wind mills and the like into a distortionless sinusoidal AC voltage of constant amplitude and constant frequency is provided. This pure sinewave inverter with line and load regulated voltage is obtained by using a combination of a hyperbolic frequency modulator (20) with a sinusoidal pulsewidth modulator (21) in the inverter circuit.
