UC3845 Lead–acid Battery SMPS Charger The board is designed as a superior power and a subordinate current regulation, which is powered from the main board. Voltage is sensed using a voltage divider directly on the output switching power supply. Current is sensed by current transformer TR2 and further streamed diode D20, and subsequently converted into…
Self-oscillating switchmode power supply SMPS is used as a simple and cheap power source. Circuits that carry the architecture of the samokmitajících converters comprising, for example, resources for the charger of mobile phones or resources for power supply of data processing. It is therefore mainly of a low power applications (up to 100 W). Flyback…
Adjustable Laboratory Power Supply SMPS design a lab power supply switching concept, which will work in kvazirezonancním fashion. The source should have one symmetrical output 0 to ±30 V / 5A (UCC28600) and one output single-ended +5V / 2A. (TOP243) Equipment opatrete digital indication of the output voltage and current and the electronic protection during…
