Abstract

PURPOSE: To improve the operating rate, reduce the size and lower the price of circuit by applying with an H-type driving method the A/C current consisting of positive and negative waves with T/4 (T; cycles) rising and lowering time to the coil for generating rotary magnetic field used for driving magnetic value.
