Abstract :
A solar battery charger using a DC/DC resonant converter with 3 reactive elements operating over a wide load range is presented. This charger is based on a half bridge inverter structure and it can be fed by a solar panels system configured as two current sources, An experimental 100 W/250 kHz unit was built and tested in the laboratory. The operation has been verified with a rechargeable lead-acid battery of 12 V and 1.2 Ah and a HP 6030A DC current source of 200 V and 17 A controlled by a personal computer. The current source follows the characteristic curve of the solar panels
