Abstract:

In order to improve the efficiency of high-frequency transformer in the high frequency link AC-DC matrix converter, an optimization design method is proposed in the converter. In this method, power loss reduction is selected as the optimization objective with the constraints of the volume, leakage inductance, and temperature rise of the transformer, which are based on genetic algorithms. Simulation and experimental results verify that the input and output performances of the transformer based the optimized design have been well improved. The maximum efficiency of the high-frequency transformer reaches 99.27%. Compared with conventional design, the total loss of the transformer is reduced by more than 30%, which proves the effectiveness of the proposed optimization design method of high-frequency transformer.

I. Introduction

The high frequency link AC-DC matrix converter (as shown in Fig. 1) is a new topology derived from the AC-DC matrix converter, which has advantages such as bidirectional power flow, unity input power factor, and high power density [1] - [2]. Because of the special topology structure, the high-frequency transformer excitation is extremely complex, which makes it more difficult to design the transformer through simple theoretical calculations and using the finite element simulation [3] - [4]. Hence, the global optimization of the transformer is very difficult to achieve. It is necessary to develop new design methods.
