Abstract
Interfering effects of output ripple on measurement of output voltage and output current in a switched power converter may be obviated by taking sampled measurements at time points which are synchronized to the cause of the output ripple to drop out. Different waveform features within the switch driving signal may be used as synchronization markers for respectively determining when to take measurement samples of converter output voltage and converter current.
