図1は本発明の実施の形態1に係る電力変換装置を中心とするシステム等の構成の一例を示す図である。はじめに、図1における高効率に電力変換を行うことができる電力変換装置を有するシステム構成について説明する。
図11は実施の形態2に係る電力変換装置の構成の一例を示す図である。図11において、実施の形態1と同様の機器、素子等については同一符号を付す。図11におけるチョッパ回路6は、リアクタ3a、短絡手段4a、逆流防止素子5aで構成したチョッパ回路に、リアクタ3b、短絡手段4b、逆流防止素子5bからなるチョッパ回路を並列に接続した構成となっている。そして、逆流防止素子5a、5bには転流手段7を接続している。このため、本実施の形態においては、2つのチョッパ回路における転流手段7は共通としている。
図16〜30は本発明の実施の形態3に係る電力変換装置の構成の一例を示す図である。同様の動作を行う手段、素子等については、実施の形態1等で説明した図面と同一符号を付している。上述した実施の形態1、2では、単相の交流電源に接続され、電源を整流した後段で短絡手段を設けた電力変換装置について述べた。この他、例えば図16〜30に示すような、単相交流電源に対応した電力変換装置についても、転流手段7を設け転流制御を行うことで上記同様の効果が得られ、この転流手段7に故障が起きた場合でも装置を保護し、信頼性を向上する効果を得ることができる。このとき、例えば図16のように、整流素子2a等を逆流防止素子として転流手段7を設けるようにしてもよい。
また、図17は短絡手段4の構成の一例を示す図である。例えば図17(a)では、整流素子41a〜41dをブリッジ接続した短絡用整流回路41と、短絡用スイッチ42とで短絡手段4を構成している。図17(a)は短絡用スイッチ42として例えばIGBTのような双方向に電流を流せない素子を1つ用いる場合における一般的な構成を示している。他にも、図17(b)に示すように、例えばIGBT(絶縁ゲートバイポーラトランジスタ)、MOSFET(電界効果トランジスタ)等を複数個用いて構成する双方向スイッチ等で短絡手段4を構成してもよく、同様の効果を得ることができる。
図31〜図40は本発明の実施の形態3に係る電力変換装置の構成の一例を示す図である。同様の動作を行う手段、素子等については、実施の形態1等で説明した図面と同一符号を付している。上述した実施の形態1〜3では、単相の交流電源に対応した電力変換装置について述べてきた。この他、例えば、図31〜図40に示すような、三相交流電源対応の同様の方式の電力変換装置についても、転流手段7を設け転流制御を行うことで上記同様の効果が得られ、この転流手段7に故障が起きた場合でも装置を保護し、信頼性を向上する効果を得ることができる。
図41は本発明の実施の形態5に係るモータ駆動装置の構成の一例を示す図である。本実施の形態では、上述した電力変換装置を介した電力供給を行う負荷として、図41に示すようなインバータ回路90とモータ91とを接続する。また、インバータ回路90の動作を制御するインバータ制御手段92を有する。本発明に係る電力変換装置を適用することで、高効率、高信頼性であり、さらにこれらに設けた転流手段7に故障が起きた場合でも装置を保護し、信頼性を向上する効果を得ることができる。ここで、本実施の形態のようなモータ駆動装置において、前段の電力変換装置において転流手段7の異常を検出した場合には、インバータ制御手段92は、モータ91での負荷が小さくなるようにインバータ回路90の動作を調整するようにしてもよい。
図42は本発明の実施の形態6に係る冷凍空気調和装置の構成の一例を示す図である。本実施の形態では、上述した実施の形態5におけるモータ駆動装置を、空気調和装置の圧縮機、送風機の一方または双方に適用する場合について説明する。
