Research Of High Voltage Changing Current Valve For The Commutatorless Motor

The commutatorless motor will be applied widely in the domain of industry and mining enterprise for saving energy in motor timing, for example in steam electric plant. In the paper, on the basis of research of static state and transient state in the SCR and series connection valve circuit, the high voltage SCR changing current valve device has been developed for AC-DC-AC high voltage commutatorless motor. The series connection valve circuit has been designed and simulated. The hardware design and software programming of trigger pulse system and monitoring system in the photo-electronic-photo fashion has been completed. And the whole device has been tested successfully.
