摘要： In a power supply with a boost pre-regulator and power factor correction devices the voltage induced in an auxiliary winding magnetically coupled to the inductor of the pre-regulator and rectified by a diode bridge charges an integrating capacitor, shunted by a discharging resistor, to a voltage which compared with predetermined reference voltages allows to detect and to signal anomalous operative conditions, such as overload or unoperativeness of the power factor correction devices for the execution of suitable intervention procedures.
