Circular convolution a method for DC-DC switching converters nonparametric characterization
This work deals with PWM switching regulator's frequency characterization in the time domain. The circular convolution measurement method is analyzed and implemented by means of virtual instrumentation. Laboratory test on a buck and a boost switching converters are performed in order to evaluate this method in terms of quality indexes such as accuracy and measurement time.
