Abstract

In this paper, the construction of a new power electronics instrument, dynamic electronic load simulator (DELS), is presented. A high-performance full-bridge power amplifier with two-stage output filter and 50 kHz switching frequency is designed for high bandwidth current loop requirement. The control of the proposed DELS mainly consists of an inner current controller and an outer load-model controller (LMC). Through the simulation and experiments, it is verified that the proposed DELS can replace a lot of RLC power components, exhibit the load behavior approximately and save a large amount of energy during burn-in test
