Abstract

PURPOSE:To eliminate a starting inability caused by overcurrent by making DC excitation at first and accelerating with AC after elapsing a specific time in the time of starting. CONSTITUTION:Commercial power is supplied to a 3 phase induction motor 5(a) for driving of a ventilator 5 through a converter 1, a smoothing condenser 2 and an invertor 3. When a starting command is inputted, the invertor 3 is controlled so that DC excitation 5(a) can be available for certain time specified in advance. After that, the starting is completed by accelerating to the extent of voltage V and frequency f commensurate with the speed command N. According to the constitution, a countermeasure against a starting inability can be attained by only a modification of a microcomputer soft for an invertor control circuit.
