The quality of power is degrading day by day due
to heavy use of non-linear loads. Power factor is a measure of
effectiveness of electricity usage.AC-DC converters are modified
to operate as power factor correction circuit In this paper, a
novel control al�orithm is developed to provide power factor
correction(PFC) of air condition loads so as to optimize its
operation. Novel al�orithm also aims at controllin� the output
volta�e and speed of compressor motor. Proposed desi�n
provides a simple, compact and low cost converter with low
volta�e stresses. This paper presents the evaluation of a constant
frequency active clamped flyback converter for PFC. The work is
simulated and analyzed in MA TLAB.
