Title:
ELECTRONIC CIRCUIT FOR AN ENERGY SUPPLY DEVICE, ESPECIALLY FOR A CHARGING DEVICE FOR BATTERIES
Document Type and Number:
WIPO Patent Application WO2002001694
Kind Code:
A3
Abstract:
The invention relates to an electronic circuit for an energy supply device (1), especially for a charging device (2) for batteries (3). The energy supply device (1) is connected to an energy source (6) by input terminals (4, 5). Said energy supply device (1) converts the energy supplied to it from a given voltage, especially an alternating voltage, into a direct voltage and releases this converted energy to a consumer (9), especially to the accumulator (3), through output terminals (7, 8). A switching element (10) is provided for polarity reversal protection. This switching element (10) is located between at least one output terminal (7, 8) and a potential, especially a negative potential, of the energy supply device (1). The switching element (10) is switched through when a particular polarity is present at said output terminal (7, 8) and is switched off when an opposite (incorrect) polarity is present. The output terminals (7, 8) are separated from the input terminals (4, 5), especially from the energy source (6), by the energy supply device (1).
