| description | To provide a control circuit of a power converter capable of determining whether or not a pulse command generator 112 is normal.SOLUTION: A control circuit 50 is applied to a system having first and second shutoff switches 23a and 23b provided in electric paths 22H and 22L that connect a high-voltage power supply 30 and a switching device unit, a smoothing capacitor 24 connected to the electric paths, a discharge resistor 26 connected in parallel to the smoothing capacitor 24, and a series connection body in the discharge switch 27. The control circuit 50 includes: a pulse command generating unit 112 that outputs a driving command SgG of the discharge switch 27, based on a discharge command CmdAD of a microcomputer 60; a driving circuit 113 that performs drive control of the discharge switch 27, based on the output driving command SgG; and an operation detection unit 114 that detects a gate voltage Vgs of the discharge switch 27. The microcomputer 60 determines whether or not the pulse command generation unit 112 is normal, based on the detection signal of the operation detection unit 114.SELECTED DRAWING: Figure 7
【課題】パルス指令生成部１１２が正常であるか否かを判定できる電力変換器の制御回路を提供する。【解決手段】制御回路５０は、高圧電源３０とスイッチングデバイス部とを接続する電気経路２２Ｈ，２２Ｌに設けられた第１，第２遮断スイッチ２３ａ，２３ｂと、上記電気経路に接続された平滑コンデンサ２４と、平滑コンデンサ２４に並列接続された放電抵抗体２６及び放電スイッチ２７の直列接続体とを備えるシステムに適用される。制御回路５０は、マイコン６０の放電指令ＣｍｄＡＤに基づいて、放電スイッチ２７の駆動指令ＳｇＧを出力するパルス指令生成部１１２と、出力された駆動指令ＳｇＧに基づいて、放電スイッチ２７の駆動制御を行うドライブ回路１１３と、放電スイッチ２７のゲート電圧Ｖｇｓを検出する動作検出部１１４とを備える。マイコン６０は、動作検出部１１４の検出信号に基づいて、パルス指令生成部１１２が正常であるか否かを判定する。【選択図】 図７ |
