WebThe precharge circuit 108 controls charging of a DC bus capacitor CDC of the DC bus circuit 114, for example, during system power up. In the illustrated three-phase system, the precharge circuit 108 is a single phase SCR-based implementation, including an SCR and a diode for each of the three input phases. WebApr 27, 2011 · So an 800 R precharge resistor would limit the current to 0.5 A, in which case 3 time constants (95% charge) would be 3 * 800R * 800uF = 1.92 seconds, which is acceptable. The suitable reed relay was a Coto 5503-12-1 which is about $28 from Digikey or OnlineComponents, but neither have it in stock. by66667
