〔課題〕提供一種可以提高電源功率因數,同時使電源高次諧液適合於IC規格,或使之可以充分靠近該規格之電力變換裝置及使用該裝置之空調機。
〔解決手段〕
電力變換裝置乃備有:將來自交流電源所供給之交流電壓整流‧平順變換為直流電壓之順變換部,及將被變換之直流電壓變換為交流電壓而供給於負荷之逆變換部,及串聯地連接於順變換部之電源側之電抗器,及介著電抗器而將交流電源強制地短路通電之昇壓電路,隨應交流電源之電壓、電抗器之電感,順變換部之電路構成及輸入電力之中之一個或複數之相異來設定昇壓電路之短路通電時間。
空調機乃使用該電力變換裝置而驅動形成冷凍循環之壓縮機者。(選擇圖)圖1
This invention provides a power conversion apparatus capable of improving the power factor of the power supply and making the harmonic component of the power supply match or very closer to the IEC standard, and an air conditioner using the same. The power conversion apparatus includes a conversion section for rectifying and smoothing an AC voltage supplied from an AC power supply and converting the AC voltage into a DC voltage, an inversion section for converting the DC voltage prepared by conversion into an AC voltage and supplying the AC voltage to a load, a reactor series-connected to the power supply side of the conversion section, a booster for forcibly short-circuiting the AC power supply via the reactor, and a controller for setting the short-circuiting conduction time by the booster so as to optimize the power factor of the AC power supply in accordance with any one or a plurality of differences between the voltage of the AC power supply, the inductance of the reactor, the circuit arrangement of the conversion section, and an input power. The air conditioner drives a compressor for forming a refrigeration cycle using the power conversion apparatus.
