WebTo make this circuit safe we need to provide a symmetric current path to discharge the capacitor when Vcc - GND is negative. This can be easily done by adding D4-D5-D6 and LED2 as in the schematic. When Vcc - GND is positive, current will flow only via D1-D2-D3 and LED1. When Vcc-GND is negative, current will flow only via D4-D5-D6 and LED2. WebJun 10, 2014 · Re: Discharging large capacitors in linear supply. A very simple way would be a relay that decouples a resistor when power supply is turned on. When power supply turns off, relay disconnects and resistor is put in contact with the large capacitor. Or use latching relay, but then your logic has to send signal to switch relay right before psu … common parts of steering system https://richardrealestate.net
