CONSUMPTION POWER FEEDBACK UNIT FOR POWER ELECTRONICS BURN-IN TEST

Power electronic burn-in testing consumes a huge amount of energy and adds up to a significant part of the manufacturing cost, To improve th is situation, a pulsewidth modulation (PWM) dc/ac inverter using curre nt-mode control is proposed to feed back burn-in test power to the uti lity system, To implement the proposed idea, a new control strategy an d system design are presented in this paper, Case studies using uninte rruptible power systems (UPS's) and battery chargers are demonstrated by means of prototype experiments to prove its performance and effecti veness.
