PURPOSE:To stabilize the operation of an inverter device by connecting the output terminal of a converter to the input terminal of a lattice type filter, and connecting the output terminal of the filter to the input terminal of the inverter, thereby fully utilizing the both characteristics of a voltage type inverter and a current type inverter. CONSTITUTION:The output terminal of a converter 2 is connected to the input terminal of a lattice type filter which is composed of two reactors 3, 4 and two capacitors 5, 6, and the output terminal of this filter is connected to the input terminal of an inverter 7. According to this configuration, the terminal voltage becomes constant even under the abrupt load variation condition, and the circuit operation is stabilized even under the load opening and shortcircuiting conditions. |
