Abstract


A number of topologies are available for the inverter of Uninterrupted Power Supply (UPS). It is desirable that the inverter output should maintain a near-sinusoidal waveforrn. Of the various techniques developed, the high-frequency link Some Pulse Width Modulation (SPWM) is most popular in compact, low-power category. In this paper., a new technique to generate low Total Harmonic Distortion (THD) sine wave form the low voltage battery bank is presented. A number of distinct advantages of this technique over existing also discussed.

Keywords


UPS; sine wave inverter; high frequency conversion.
