Abstract

This article present charge equalized module using quasi-resonant flyback converter with DC-link bus strategy. With this technique, turn on switching loss is decrease by 71 percent. Switching at low voltage and operating at low dv/dt, the electromagnetic interferences are also decline. By applied this proposed technique to the charge equalized system, the unbalance charging problem can be eliminated. The validity of this approach can be supported by computer simulation and experimental result. ฉ 2010 IEEE.
