Abstract
Description
ゲート駆動ユニット(GDU:Gate Driver Unit)はゲート基板を含む。ゲート基板は、電力変換装置の外部にある制御装置から入力された制御信号を絶縁し、絶縁された制御信号をゲート信号に変換して出力するためのゲート駆動回路部品を搭載している。
第1の基板31は、ゲート基板に相当し、ゲート駆動回路部品311を搭載する。ゲート駆動回路部品311は、接続端子312を介して接続された制御回路(図示せず)から入力された制御信号を絶縁し、絶縁した制御信号を、パワーモジュール2を駆動するゲート信号に変換して出力する回路部品である。なお、制御回路から入力される制御信号は、PWM(pulse width modulation)信号であってもよい。
前述したように、第1の基板31と第2の基板32との間のゲート制御線としては、例えば、配線インダクタンスを低減するためにゲート配線とソース配線(グランド配線)とを絶縁シートを介してラミネート構造にした配線導体板が知られている。仮に、こうした配線導体板にコネクタを接続し、配線導体板をコネクタを介して第1の基板31及び第2の基板32と接続すると、配線インダクタンスを低減する効果が薄れてしまう。そこで、こうした配線導体板は、はんだ等を用いて、第1の基板31及び第2の基板32の各端子(ピン)と直接接続することが望ましい。しかしながら、配線導体板が、はんだ等を用いて第1の基板31及び第2の基板32の各端子と固着されると、ゲート駆動回路部品311が搭載された第1の基板31と、第2の基板32が固着されたパワーモジュール2とを、電力変換装置1への実装後に容易に分離できない。
まず、ゲート制御線332は、第1のコネクタ3311と第2のコネクタ3312との間のゲート配線3321とソース配線3322との撚線であってもよい。ゲート制御線332に含まれるゲート配線3321とソース配線3322とが撚線にされることによって、ゲート配線3321及びソース配線3322に流れる電流によって発生する磁界は打ち消し合う。それ故、ゲート制御線332のインダクタンスを低減できる。
例えば、接続部材33は、ゲート制御線332を含まなくてもよい。すなわち、図8に示すように、接続部材33は、第1のコネクタ3311´と第2のコネクタ3312´とが直接相互に接続されるように構成してもよい。図8は、実施形態に従った電力変換装置の接続部材の別例を示す図である。こうした構成によっても、ゲート駆動回路部品が搭載されたゲート基板と、ゲート中継基板が固着されたパワーモジュールとを含む電力変換装置において、ゲート基板とパワーモジュールとを電力変換装置への実装後に容易に分離できる。
