Color synchronous signal is setup to resume subcarrier color signal as same frequency and phase in receive end, which is suppressed in send end.
色同步信号是为了在接收端恢复与发送端被抑制掉的色副载波同频同相的载波而设置的。
Moreover, synchronous switch is applied to the system in order to complete the smooth switch on condition that frequency and phase of inverter power and power supply are the same.
同时利用同步切换控制实现水泵由变频电源向工频电源的平稳切换。
