ABSTRACT:
First and second rectifiers (37), (41) have inputs connected to an A.C. power source (12) through a unitary switch (33) and outputs connected to first and second smoothing filters (38), (42) respectively. An inductance (39) is connected between the switch (33) and the first rectifier (37) whereas a capacitance (43) is connected between the switch (33) and the second rectifier (41). The values of the inductance (39) and capacitance (43) are selected in such a manner that surge currents through the capacitance (43) and inductance (39) occuring when the switch (33) is closed are limited and the power factor of the power supply (31) is maximized.
