Development of digital burn-in test plant for DC-DC converter with energy recycling considered

An active load for the burn-in test of the DC-DC converter, possessing multiple inputs with a wide range of input voltages, is proposed herein, whose controller is realized by a digital signal processor (DSP). By means of DSP, data monitoring and command setting are easy to realize. First of all, the details of the proposed circuit topology and the corresponding control strategy are presented. Finally, some experimental results are provided to demonstrate the proposed burn-in test plant.
