Description
(第1実施形態)
以下、第1実施形態について図1〜図6を参照して説明する。
|Q1−Q2|<|Q1| …(1)
上記(1)式の左辺は、デッドタイム中におけるインバータ主回路7での消費電荷の変化量とデッドタイム中における電源回路9での消費電荷の変化量との差の絶対値であり、電流調整動作を実施した場合におけるモータ駆動装置3の消費電流の変動分を表している。一方、上記(1)式の右辺は、デッドタイム中におけるインバータ主回路7での変化量の絶対値であり、電流調整動作を実施しない場合におけるモータ駆動装置3の消費電流の変動分を表している。
Ic=I2H−Iout …(2)
Id=I2L−Iout …(3)
Ic=(T2/T1)・Id …(4)
Vout1H−Vout1L=Ic・T1/C3 …(5)
I2L=0 …(6)
I2H=C3・(1−T1/T2)・(Vout1H−Vout1L)/T2 …(7)
本実施形態のモータ駆動装置3は、電源線Ldから電源回路9への電流供給量を調整する電流調整回路10を備えている。そして、制御回路8はハーフブリッジ回路12〜14の動作状態に応じて、電流調整回路10の動作を制御する。具体的には、制御回路8は、ハーフブリッジ回路12〜14からモータ2に供給される電流が減少する方向に変化したときに電源回路9への電流供給量が増加するように電流調整回路10の動作を制御する。このようにすれば、モータ2に供給される電流の減少分が電源回路9への電流供給量の増加分によって補われ、その結果、モータ駆動装置3に流れる電流の変動が抑制される。
以下、第2実施形態について図7および図8を参照して説明する。
図7に示すように、本実施形態のモータインバータ41のモータ駆動装置42は、第1実施形態のモータ駆動装置3に対し、制御回路8に代えて制御回路43を備えている点、電流調整回路10に代えて電流調整回路44を備えている点などが異なる。

以下、第3実施形態について図9および図10を参照して説明する。
図9に示すように、本実施形態のモータインバータ51のモータ駆動装置52は、第1実施形態のモータ駆動装置3に対し、制御回路8に代えて制御回路53を備えている点、電流調整回路10に代えて電流調整回路54を備えている点、電源回路9に代えて電源回路55を備えている点などが異なる。
以下、第4実施形態について図11および図12を参照して説明する。
図11に示すように、本実施形態の制御回路61は、図5に示した第1実施形態などの制御回路8に対し、制御部31に代えて制御部62を備えている点、NOR回路35に代えて抵抗R61〜R64およびOPアンプ63を備えている点などが異なる。
なお、本発明は上記し且つ図面に記載した各実施形態に限定されるものではなく、その要旨を逸脱しない範囲で任意に変形、組み合わせ、あるいは拡張することができる。
上記各実施形態で示した数値などは例示であり、それに限定されるものではない。
本発明のモータ駆動装置は、モータ2を駆動するための3相のインバータ主回路7を備える構成に限らずともよく、例えば直流モータを駆動するためのHブリッジ回路を備える構成など、少なくとも1つのハーフブリッジ回路を備えた構成であればよい。
