An efficient automatic testing algorithm for power supplies in electronic systems

Since power supplies of electronic systems are important parts to operate without stopping, they are checked periodically and replaced when accidental failures are expected. Moreover it is required, in critical applications, to predict when the power supply will fail. Automatic testing equipment (ATE) described in this paper implements algorithms for testing various power supplies. This algorithm is based on the classification of characteristics and testing items of power supplies which have an AC input and DC outputs
