To provide a link capacitor discharge circuit with temperature control.SOLUTION: According to at least some embodiments, a discharge circuit for an electric vehicle includes: a link capacitor; a resistance load; a discharge switch that is coupled to the link capacitor and the resistance load, in which the link capacitor is coupled to the resistance load when the discharge switch is closed to enable discharge of the link capacitor; and a discharge interruption assembly. The discharge interruption assembly includes: a detection resistor that is serially connected to the resistance load; and a temperature circuit. The temperature circuit includes an input connected to the detection resistor and an output. A discharge interruption circuit is responsive to a voltage in the output of the temperature circuit in order to open the discharge switch when the voltage from the temperature circuit is higher than a threshold value.SELECTED DRAWING: Figure 2
【課題】温度制御を伴うリンク・コンデンサ放電回路を提供すること。【解決手段】少なくともいくつかの実装形態では、電気車両のための放電回路は、リンク・コンデンサと、抵抗負荷と、リンク・コンデンサ及び抵抗負荷に連結される放電スイッチであって、リンク・コンデンサの放電を可能にするために放電スイッチが閉鎖された際にリンク・コンデンサが抵抗負荷に連結されるようにする、放電スイッチと、放電遮断組立体とを含む。放電遮断組立体は、抵抗負荷と直列に接続される検知抵抗器と、温度回路とを有する。温度回路は、検知抵抗器及び出力に接続される入力を有し、放電遮断回路は、温度回路からの電圧が閾値より高い場合に放電スイッチを開放するため、温度回路の出力における電圧に応答する。【選択図】図2
