#142672 - Its a three phase bridge rectifier Responding to: ???'s previous message |
Thanks for the expert advices. I just got NTC thermistor to suppress the inrush. That may also help in PFC. (probably)!
Kai, the bridge rectifier here is not for the single phase but for three phase. so, 10ms is not the charging time, I guess, but rather 3.33ms would be the correct one (since three phase bridge is six pulsed). When I checked cap. voltage on scope, I found that there are ripples but what really surprised me was to see decreasing peak voltage level as the load increased. It seems that when load increase, capacitor is not being able to get charged fully. Is there anyway (any "practical" method) to decrease the ripple (to make capacitor voltage more constant)? (surely, I am not for 100A charging now)! |
