On idle, using the voltage-feedback control makes PWM modulator output the pulse disjointedly with blocking-oscillation frequency lowered and the pulse width narrowed. Accordingly not only the no-load loss is less, but also the transformer is not easy to saturate.

系统在空载时由于采用电压反馈控制使PWM调制器间断地输出脉冲,间歇振荡的频率低而脉冲宽度窄,不但空载损耗小,而且使变压器不易饱和;

The pulse control strategy is to control pulse frequency based on expected voltage output frequency, so as to realize no system high frequency and avoid the PWM strategy.

脉冲控制策略以期望的电压输出频率控制脉冲频率,实现系统无高频,避免了脉宽调制。

Change the inverter output voltage or output current are two kinds of different ways, namely, PAM pulse amplitude modulation control and PWM control pulse width modulation.

改变变频器的输出电压或输出电流有二种不同的方法,即PAM脉冲幅值调制控制和PWM脉冲宽度调制控。

The analyses show that overvoltage is a function of the rise time of the converter output pulse and the lengths of the traction motor cables, and that its magnitude can be as large as 1.9 times of the pulse voltage.

研究结果表明,变频牵引电机端子过电压由脉冲上升沿时间和电缆长度共同决定,其幅值最大可达脉冲电压的1.9倍。
