ABSTRACT:
Paralleled DC power supplies each comprise a half-bridge, resonant inverter (19-23) feeding a converter (25-28) connected to a common load 8. Current mode control (50-54) is provided (36) through a PWM IC (30) to which the output voltage (31) is fed back. Inverter capacitor imbalance is corrected (52, 55-59). Load sharing (71) is accommodated with offset compensating bidirectional buffer amplifier circuits (65-70, 74-76).
