Title:
BATTERY CHARGING PROCESS FOR VEHICLES
Document Type and Number:
Japanese Patent JPS53123849
Kind Code:
A
Abstract:
A road vehicle battery charging system for a dual voltage electrical supply includes a conventional alternator/rectifier assembly for charging a main battery and a d.c. to d.c. converter for charging an auxiliary battery in series with the main battery. The converter includes two transistors connected with a feedback transformer to form an oscillator to drive an output transformer. The oscillator includes two diodes which need to be connected to one terminal of the main battery to allow the oscillator to run and a switching transistor is interposed in such connection and has its conduction controlled in accordance with the alternator output so as to inhibit the d.c. to d.c. converter when the alternator output is below a predetermined level.
