I am engineer who develop and design magnetic component, if you have magnetic component question, would you please kindly contact with me, I will try my best to help you.
please can u kindly explain how to design a lowpass filter for an spwm inverter with carrier frequency of 5Khz and modulating frequency of 50hz. fundamental frequency being 50hz. 240v 5amps.
Typical design parameters for a lowpass filter are shown in Fig.4.2.
Figure 4.2: Illustration of typical lowpass filter specifications in the frequency domain.
The design parameters are defined as follows:
stop-band ripple ( dB is common)
pass-band ripple ( dB typical)
stop-band edge frequency
pass-band edge frequency
TW: transition width
SBA: stop-band attenuation
