I want to extract the 50Hz fundamental frequency component or DC component of the voltage at the shunt point in a double closed loop control of an inverter. As far as I know, a low pass filter or a notch filter can be used. But the lower the cutoff frequency, the greater the signal delay between input and output. Is there a good way to solve the delay problem?I want to extract the 50Hz fundamental frequency component or DC component of the voltage at the shunt point in a double closed loop control of an inverter.
