Abstract

889,306. Battery charging systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. Aug. 19, 1958 [Aug. 22, 1957], No. 26641/58. Class 38 (4). A battery charging apparatus operable from a number of different A.C. or D.C. voltage sources has a comparison device to connect the source to the battery only when the supply and battery voltages are in correct relationship. A transformer 2 primary winding is connected by a voltage-selecting switch SI-SVI to a source 6, to which is also connected a bridge rectifier 8 supplied through a capacitor 22 which operates a relay W on A.C. supplies, the relay being protected by a shunt connected voltage dependent resistor 23. Operation of relay W disconnects through a contact w1 a vibrator unit 1 whose driving coils 4, 5 may be connected in series or parallel. A polarized relay P has a coil 16 connected to the source through a rectifier 15 and one of resistors 9-11, and an opposing coil 17 connected to the battery 7 so that when the currents to the windings are similar, a contact p operates through a transistor 20 a relay A, whose contacts al, a2 connect the transformer 2 to the source, and the battery 7 to a rectifier 3 fed from the transformer secondary winding respectively. A capacitor 25 and choke 26 smooth the rectifier 3 output. The relay P only operates when the source voltage and battery voltage are in correct relationship, hence neither of these voltages need be known, also when the battery voltage rises or falls beyond determined values it is also disconnected.
