8-4. Output Rectifying and Smoothing Circuit
The fly-back voltages which are generated at the secondary windings of T601 are rectified by D6A1, D6E1,
D6F1, D6G2, D6H1 and D6K1. Then, these voltages are smoothed by C6A1, C6A2, C6E1, C6E2, C6F1,
C6F2, C6F3, C6G2, C6H1, C6H2, C6K1 and C6K2 so that DC voltages are obtained.
The DC voltages are maintained constantly by controlling the ON period duty cycle of TR1 (internal IC621) in
the converter circuit.
