  • Publication number: 20200259410
    Abstract: A power supply protection circuit is a circuit that controls a protection switch provided on a power supply line connecting a direct current power supply and a load circuit. The power supply protection circuit includes: circuitry connected to the protection switch; and a controller that switches an operation state of the circuitry between a first state and a second state. The first state is an operation state in which driving of the protection switch is enabled when the protection switch is a first semiconductor switch having a control terminal connected to a semiconductor layer of a first conductivity type. The second state is an operation state in which driving of the protection switch is enabled when the protection switch is a second semiconductor switch having a control terminal connected to a semiconductor layer of a second conductivity type that is different from the semiconductor layer of a first conductivity type.

  • Patent number: 10536074
    Abstract: A power-factor correcting converter includes: a series circuit including a first higher-potential switch and a first lower-potential switch connected in series to each other; and another series circuit including a second higher-potential switch and a second lower-potential switch connected in series to each other. In a positive phase period of the input AC voltage, a control circuit turns off the second higher-potential switch, turns on the second lower-potential switch, and alternately turns on and off the first lower-potential switch as a master switch and the first higher-potential switch as a slave switch. In a negative phase period of the input AC voltage, the control circuit reverses the on/off operation and the master/slave relationship, and turns on and off only the master switch and turns off the slave switch when the absolute value of the input AC voltage is smaller than or equal to a predetermined value.
