Abstract
PURPOSE: To simplify the carcuitry by obtaining 3-phase AC current having a frequency equivalent to 60% of the power supply frequency direct from the 3-phase current power source.
CONSTITUTION: The first electric valves 31∼33, the second electric valves 41∼43 and the third electric valves 51∼53 are respective by provided between the 3-phase AC current power source 1 and respective phases of a 3-phase load 2. The first to third electric valves provides energization between respective phases of the 3-phase AC current power source 1 and respective phases of the load 2 in sequence. With such an arrangement, it is possible to obtain a 3-phase AC power ballanced by a frequency equivalent to 50% of the frequency of the 3-phase AC power source 1.
