摘要： Herein described is a control device of a device for the correction of the power factor in forced switching power supplies; said device for the correction of the power factor comprises a converter and said control device is coupled to the converter to obtain from an alternating input line voltage a regulated output voltage. The control device comprises generating means associated to a capacitor for generating a signal representative of the root-mean-square value of the alternating line voltage; the generating means are associated to means for discharging said capacitor. The control device comprises further means for discharging the capacitor suitable for discharging said capacitor when the signal representative of the root-mean-square value of the alternating line voltage goes below a given value.

摘要： A control device of a switching converter having an input terminal, an output terminal and a semi-bridge of a first and second transistor coupled between the input terminal and a reference voltage, includes a first circuit for detecting a signal representative of the signal on the converter output terminal and able to compare it with a reference signal and to emit a first signal in response to the comparison. The control device drives the first and second transistors based on the first signal and includes a protection circuit to detect the presence of overcurrents in the semi-bridge and acting upon the first and second transistors in response to the detection. The control device includes a second circuit for acting upon the first circuit in order to level the value of the first signal after the triggering of the protection circuit.
