| Power factor corrector technology is one of the main technologies of power electronics. It is a key part of switch mode power supply.Boost converter topology can reach high power factor performance. But, this circuitry has a reliability issue. When mains voltage increases too high, it will damage the power electrical equipment due to high current flow.Based on analyzing the PFC technology theory, one solution is proposed. Both Pspice simulation result and hardware testing result are good. |
