  • Apparatus for controlling in-vehicle heater
    Patent number: 9821635
    Abstract: In order to perform overheating protection of a controller for water-heating heaters 3A and 3B for in-vehicle heating, an energization circuit for a heater 3 (3A, 3B) includes IGBTs 11 and 12 as switching devices that are disposed therein to be in series with the heater 3, and a first temperature sensor (first thermistor) 21 which measures temperature of these IGBTs 11, 12. A comparator 25 is provided to transmit a signal when the temperature of the IGBTs 11, 12 is equal to or greater than a predetermined temperature. Then, the IGBTs 11, 12 can be forcibly turned OFF via the IGBT driver 13 in response to a signal from the comparator 25 without a microprocessor 14 intervening therebetween.

  • Apparatus For Controlling In-Vehicle Heater
    Publication number: 20150122899
    Abstract: In order to perform overheating protection of a controller for water-heating heaters 3A and 38 for in-vehicle heating, an energization circuit for a heater 3 (3A, 38) includes IGBTs 11 and 12 as switching devices that are disposed therein to be in series with the heater 3, and a first temperature sensor (first thermistor) 21 which measures temperature of these IGBTs 11,12. A comparator 25 is provided to transmit a signal when the temperature of the IGBTs 11,12 is equal to or greater than a predetermined temperature. Then, the IGBTs 1112 can be forcibly turned OFF via the IGBT driver 13 in response to a signal from the comparator 25 without a microprocessor 14 intervening therebetween.
