求翻译：系统采用PWM波控制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？

PWM wave control system uses complementary power transistor turn-on signal generated SPWM inverter, the inverter signal through the LC low-pass filter, you can get high-power sinusoidal signal.

The control system adopts PWM complementary transmission power control signals generated SPWM inverter, the inverter LC signal through low-pass filter, you can get high-power sine signal.

The system uses the PWM wave control 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 control using PWM wave power tubes complementary on-SPWM inverter signal after the inverter signal through LC low-pass filter, you can get large power sinusoidal signals.

The system adopts PWM unexpected turn of to control the power to be in charge of leading and producing SPWM to go against and turn openly into the signal complemental, should be after being against turning into the signal and passing LC low coherent electric-wave filter, can receive the sine signal
