求翻译：系统采用PWM波控制正弦脉宽逆变电路中的功率管互补导通产生SPWM逆变信号，该逆变信号通过LC低通滤波器后，便可得到大功率正弦信号。是什么意思？

Sine wave PWM control system uses a pulse inverter circuit in the power tubes produce complementary conduction signal SPWM inverter, the inverter signal through the LC low-pass filter, you can get high-power sinusoidal signal.

Control systems use PWM sine wave pulse width inverter circuit in the complementarity of the generated power inverter SPWM signal, the inverter signal LC through low-pass filter, you can get high-power sine signal.

The system uses in the PWM wave control sine pulse width inversion electric circuit the power tube supplementary breakover to produce the SPWM inversion signal, this contravariant signal after the LC low pass filter, then may obtain the high efficiency sine signal.

System adopt PWM wave control sine pulse width against turn power of circuit into in charge of lead produce SPWM go against change signal while being coherent complemental, should be after being against turning into the signal and passing LC low coherent electric-wave filter, can receive the sine si
