摘要： An inverter includes a voltage command generator generating a voltage command value according to an externally specified voltage value, a PWM signal generator generating a PWM signal according to the voltage command value and frequency command value, and a switching unit generating a three-phase AC power according to the PWM signal. The voltage command generator decreases the voltage command value if the output current increases, to prevent the rotation speed of a prime move from suddenly changing. If the output current exceeds a preset upper current threshold, the voltage command value is clamped at a preset minimum output voltage, thereby securing the minimum output voltage for an increase in the output current.
摘要翻译：逆变器包括根据外部指定的电压值产生电压指令值的电压指令发生器，根据电压指令值和频率指令值产生PWM信号的PWM信号发生器，以及产生三相交流电力的开关单元根据PWM信号。如果输出电流增加，电压指令发生器会降低电压指令值，以防止原点转动的转速突然变化。如果输出电流超过预设的上限电流阈值，则电压指令值被钳位在预设的最小输出电压，从而确保最小输出电压以增加输出电流。

摘要： An inverter generator includes a motor, an electric generator and an ECU generating a pulse at each predetermined rotation angle of the motor. Estimating means estimates an initial electrical angle of alternating voltage produced by the generator from the pulse and calculates a phase shift angle to estimate continuous electrical angle of the alternating voltage. A converter converts the alternating current electric power into direct current electric power under d-q control based on the phase shift angle. An inverter converts the direct current electric power into alternating current output electric power.
