专利汇可以提供Power converter专利检索,专利查询,专利分析的服务。并且PURPOSE: To make the configuration simple without regenerative inverter by constituting a converter and a control sequence so that a regenerative current is regenerated from the DC-output-terminal side of a forward converter to a power supply.
CONSTITUTION: A rotation sensor PG for sensing the rotating freuency of a rotor is directly connected to the end of the shaft of an induction motor IM which is a load. In addition to a converter-controlling circuit C, a rotation-direction-sensing circuit 47, a speed-control system 85, a flux-constant-control circuit 86, a frequency synthesizer 87, an inverter-side gate-phase-shift circuit 88, and the like are provided. To the DC-input terminals B and O of a collective-communication-type inverter, is connected a single Ward-Leonard circuit LEO as a forward converter LO. A charging diode 29 is connected between the terminal B and a capacitor 14, and a GTR 30 is also connected in inversely parallel with a diode 29.
