Abstract :
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
