Abstract
- In many power electronics products, a burn-in test for several hours is generally applied to test the basic functions and stress of the devices. As for power supplies, battery chargers, power converters, etc., power consumption during burn-in tests is generally huge, and has become a big cost adding onto the products and the manufacturers. An idea to feedback the consumption power from the load side of the burn-in test devices can be implemented to reduce energy loss and save manufacturing cost. This paper presents a new control strategy and system design for consuming power feedback. A PWM DC/AC inverter using current-mode control is proposed. Simulation of the operation of such a power consumption feedback system is conducted to show the capability and performance of the proposed idea. A laboratory prototype system is built and tested for a UPS burn-in test and a battery charger burn-in test. Experiment results as well as simulation results prove that the proposed feedback and control strategy is useful to the applications of burn-in tests for power electronics products. In this study, the system configuration of the power consumption feedback unit for different applications is modified, and its control strategy and operation is figured out with feasible analysis. Cost analysis and energy saving analysis is also discussed.
