Abstract

This paper introduces a kind of battery charger employing power MOS as complementary switches, which is controlled by integration-feedback circuit, and, the charging current changes in steps under control of micro-computer while keeps constant automatically within each step. It can charge a high-capacity battery-assembly in series connection of 18×12V. The device performances well under a wide range of AC voltage from 190V to 250V while the battery-assembly DC voltage varied from under 190V up to 250V. The performance of feedback and control circuits are discussed in detail, as well as the current´s wave pattern in key elements.
