Today, 02:45Easy peasy replied to a thread When is power too high for BCM Boost PFC and CCM Boost PFC is more efficient? in Power Electronics3 phase interleaved up to 1.6kW easily, in fact we would do 3kW this way off 230v single phase mains if we had a client call for it - low RFI...1 replies | 68 view(s)

Today, 02:39Easy peasy replied to a thread Measuring leakage inductance of flyback transformer in Power ElectronicsBest way is the resonance test, choose a good quality, hi Q, cap, say 470nF 400V ( but can be any good quality cap ) solder in parallel...2 replies | 94 view(s)

Today, 00:35Easy peasy replied to a thread Boost PFC controller must contain anti-distortion feature for zero crossings in Power Electronicsit looks to be more an artifact of the diode bridge in the sim - this is quite common to see - try putting a snubber across each diode in the sim...7 replies | 172 view(s)

23rd August 2019, 13:07I replaced the Mosfets to IRFP250N. For PWM signal > 50 kHz the output signal is getting distorted and also the HOx and LOx signals. What changes...23 replies | 547 view(s)
