EQUITY DEVICE OF ELECTRICAL POWER LOAD

摘要

a reactor (ER) for controlling the phase shift angles between a normal power source (Eu) and a power converting section (TM) by detecting the current of a current transformer (CT); and a plurality of circuits A1-A4 for controlling the power converting section (TM). The reactor (ER) controls the phase difference of an inverter (GTO), and a battery (BT) is connected in parallel with the normal power source (Eu), thereby leveling the power supply.
