摘要
In a PWM-controlled, variable voltage/variable frequency inverter (INV), a pulse mode (N), which is identified by a number of voltage pulses within one cycle of an AC output voltage of the inverter (INV), is changed in accordance with a frequency of the AC output voltage and an AC output voltage factor ( beta ), which is a ratio of an AC output voltage to be produced by the inverter (INV) at that time to a maximum value of the AC output voltage which can be produced under a then-present value of a voltage of a DC voltage source (Ed) for the inverter (INV).
