にした充電器。 A rectifier circuit using a thyristor that receives commercial sine wave voltage as input, a storage battery, and the commercial sine wave voltage and storage battery voltage as detection input and feedback input, respectively, converts the commercial sine wave voltage into a triangular wave that is phase-synchronized with this. a carrier wave, and a circuit that performs PWM control on the conduction angle of the thyristor of the rectifier circuit using the feedback input as a carrier wave, and constantly stabilizes the floating voltage of the storage battery at a constant voltage. If the triangular wave generated by the waveform conversion described above changes due to an instantaneous power outage, superimposed noise, waveform distortion, etc. of the commercial sine wave voltage that is the detection input, and this fluctuation becomes larger than a predetermined reference value, the fluctuation value of this triangular wave will change. is directly fed back to the circuit that performs the waveform conversion described above, and an instantaneous control circuit is provided that instantaneously suppresses the fluctuation of the triangular wave according to its value. Normally, when the fluctuation of the triangular wave is smaller than the reference value, The triangular wave control system is duplicated by using an average value control circuit that detects the minute value and feeds it back to the above-mentioned waveform conversion circuit, and switches between instantaneous control and average value control according to the fluctuation value of the triangular wave. A charger that enables constant PWM control of the conduction angle of the thyristor.
