Title: Improved power factor converter
Inventor: HIRAKAWA HIDEKI
IPC: H02M1/14
Filed: 1993-07-09
Abstract: PURPOSE:To allow suppression of ripples on the output by a circuitry wherein a second converter is connected in series with the secondary of a converter transformer and fed with rectified and smoothed power from the tertiary winding of the transformer and the converter control circuit is driven in response to the ripples on a voltage obtained by rectifying an AC input voltage. CONSTITUTION:An ON/OFF type converter (CV) comprises a main switching element Q1, a full-wave rectifier D1, and a capacitor C2. A transformer T1 is provided with an auxiliary winding (tertiary winding) having the same polarity as the secondary winding of the CV and a second converter, i.e. a ripple suppressing converter(CONV), is connected across the tertiary winding through a diode D3 and a capacitor C5. A control circuit(CONT) 1 detects an output voltage V1 and conducts a low response control. The output voltage V1 is vector added to an output voltage V2 from the CONV and fed to a load Z. In other words a CONT 2 detects the voltage V1+V2 and responds to the ripples on a voltage obtained by rectifying an AC input voltage.
