  • Patent number: 9136834
    Abstract: A switching apparatus that switches a connection state between two terminals, comprising a switch that switches the connection state between the two terminals according to a control voltage supplied thereto; a first power supply section that generates power supply voltage with a first voltage value; a second power supply section that generates power supply voltage with a second voltage value; and a driving section that, upon receiving switching instructions to switch the switch from a first state to a second state, uses power generated by the first power supply section to change the control voltage to be the first voltage value, and then uses power generated by the second power supply section to further change the control voltage from the first voltage value to the second voltage value, in the same direction and with a rate of change over time that is less than a rate of change over time used when changing to the first voltage value.

  • Patent number: 8947112
    Abstract: Provided is a switching apparatus that switches a connection state between two terminals, comprising a switch that switches the connection state between the two terminals according to a control voltage supplied thereto; a driving section that provides the switch with the control voltage corresponding to a control signal supplied thereto; and a changing section that changes the control voltage output from the driving section, according to a designated switching time. The changing section may change power supplied as a power supply to the driving section, according to the designated switching time. The changing section may change the control voltage output from the driving section prior to switching of the switch.
