摘要：
The disclosure is directed to a power conversion circuit (100) including a bypass circuit (70) for bypassing an inrush current limiting resistor. The power conversion circuit (100) may comprise: a bridge rectifier; at least one current limiting resistor (R ICL ; R1, R2) coupled to the bridge rectifier and an electrical ground (25); at least one controllable current switching device (72; 201, 202) coupled to the current limiting resistor (R ICL ; R1, R2); and at least one driver coupled (74; 74A, 74B) coupled to the current limiting resistor (R ICL ; R1, R2) and the controllable current switching device (72; 201, 202), the at least one driver (74; 74A, 74B) configured to control an operation of the at least one current switching device (72; 201, 202) based on a current or a voltage through the current limiting resistor (R ICL ; R1, R2).
