Abstract

PURPOSE:To contrive the omission of a smoothing reactor and the improvement of transient response speed by providing a current limiter at the primary side of a transformer. CONSTITUTION:The current limiter 30 acts to regenerate energy generated to limit the output current in an inverter circuit 10 to a DC power source 12. And the conductivity of a switching element 38 is controlled by the current flowing into a diode bridge circuit 34 and the switching element 38 is turned on when the current value detected through a current transformer 32 exceeds the value set by a current commander 44 and the energy stored in a reactor 40 is regenerated to the DC power source 12 to control the primary current of a transformer 14 to almost fixed value. And each switching element 10a-10d in the inverter circuit 10 is controlled by a conductivity regulator 28 to obtain an almost fixed output voltage on a load 20. In this way, the installation of a smoothing reactor can be omitted and transient response speed can be improved by 200 times.
