技術說明

一種電力轉換裝置適用於電連接到一馬達、一馬達反流器及一市電端，馬達電連接到馬達反流器，並在減速時經由馬達反流器提供一直流電力，電力轉換裝置包含：一直流鏈電容，儲存馬達反流器所提供的直流電力；一反流器，馬達減速時遭致能以將直流電力轉換成一轉換電力；串聯的一轉換電感與電容，電連接於市電端和反流器之間，並當馬達減速時轉換電感與電容的共同接點電壓遭轉換電力瞬間拉升，而使轉換電感的兩端壓差實質上等於轉換電力之電壓以產生一轉換電流送到市電端；及一控制電路，判斷馬達是否減速，以決定是否將反流器致能或去能 A power converting device is adapted to be connected to a motor, a motor inverter and a grid power source. The motor is connected to the motor inverter, and provides a DC power through the motor inverter when being slowed down. An inverter operable to be enabled to convert the DC power into a converted power when the motor is slowed down; a series connection of a converting inductor and a capacitor connected between the grid power source and the inverter, when the motor is slowed down, a voltage at a common node of the converting inductor and the capacitor being pulled up immediately by the converted power such that the voltage across the converting inductor is substantially equal to the voltage of the converted power to generate a converted current to the grid power source; and a control circuit for determining whether the motor is slowed down and for enabling or disabling the inverter accordingly.
