The output voltage is kept regulated using a Rectified with schottky rectifier STPS3045 and an LC filter is used toįilter to pure DC. The output of the ETD39-based transformer is ![]() Power dissipated by the 7812 is not too high and no heat sink is Voltage difference between 7812 input and output is not too great, the Rectified, filtered and regulated to 12V with a 7812 to power the (18V 100mA) is used to provide auxiliary low voltage output, which is ![]() 2 bulk capacitors (470uF, 200V each) are used for the The output signals of the SG3525 are fed intoĪ IR2110 high-low side driver which drives the 2 MOSFETs (IRF840)Ĭonfigured for half-bridge topology. Primary side PWM is controlled by SG3525 PWM chip. To be incorporated in SMPS inverter with charger. Final test circuit (on PCB) for battery charging. ![]()
