摘要： An inverter power generator includes a current controller 14a setting a current limit ratio according to a rotation speed of a synchronous motor 13 and controls a converter current according to the current limit ratio. The current controller sets the current limit ratio to 70% if the synchronous motor is at a rotational speed equal to an idle speed of an engine 11. Until the rotational speed of the synchronous motor reaches a rated speed, the output current limiter linearly increases the current limit ratio up to 100%. With this, the rotational speed of the engine becomes reasonably increasable even if a sudden load increase occurs when the engine is operating at low speed.
摘要翻译：逆变器发电机包括电流控制器14a，其根据同步电动机13的转速设定限流比，并根据电流限制比控制转换器电流。如果同步电动机处于与发动机11的怠速转速相等的转速，则电流控制器将电流限制比设定为70％。直到同步电动机的转速达到额定转速为止，输出限流器线性增加电流限制比达100％。由此，即使在发动机以低速运转时发生突然的负载增加，发动机的转速变得合理地增加。

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.

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： The user circles the fax number or name of the receiving party and the system then uses the circled number or name to dial the receiving party's fax machine to initiate the transmission. The system scans the first page or cover page of the document to be faxed and uses a computer-implemented algorithm to detect the user-circled region. The image within the user-circled region is then extracted and optical character recognition performed to ascertain the fax number. Alternatively, the user-circled region may contain a name or other information to access a database where the fax number is stored.
