average the results, and send them to the control loop. This oversampling effectively averages the current ripple out such that the measured current signal gets closer to the average current
proper losses of the Si SJ MOSFET Q1 during turn-on. If this pulse falls short, the possibility to have severe hard commutation is high in the Si SJ MOSFET, which would produce destructive results if it occurs during long periods. Similarly, the LV MOSFET could run continuously in avalanche...
A 10kHz interrupt is set in the firmware and the PI control loop is adopted for voltage loop in the design. Because PFC output voltage has two times the line frequency voltage ripple, which results in a third harmonic current, the voltage loop’s bandwidth needs be kept low enough to mini...
Figure 1. Bridge rectifier input (left) and totem-pole PFC stage (right) In the TPPFC circuit, when the AC mains connection to L1 is positive, Q1 forms the boost switch, Q2 forms a synchronous rectifier, Q3 conducts to allow line current to circulate and Q4 is blocking. When the AC...
In this solution, when VACchanges from a negative to a positive cycle after AC zero crossing, active switch Q4 turns on first with a very small pulse width, then gradually increases to the duty cycle (D) generated by the control loop. A soft start on Q4 gradually discharges the switch-no...
Applications have been tested with the filter on the AC or DC side of the diode bridge and have obtained passing results. The use of an R-C snubber to damp filter resonances and optimize TRIAC compatibility is strongly recommended. The EMI filter design involves optimizing several factors and ...
