Iron core excitation system in electric equipment, iron core excitation method in electric equipment, program and inverter power supply modulation operation setting device

摘要

Reduces the iron loss of the excited iron core by using the inverter power supply. In the inverter power supply modulation operation setting device 1430, the loss of the entire system (iron loss, copper loss, and switching loss) is a target waveform (not including harmonics) and the loss of the entire system when the electric device is operated. To be less than that, the maximum value Hmax and the minimum value Hmin of the magnetic field strength H in the minor loop are controlled.
