Korea put the company at electric power control device - the general type STR (thyratron thyristor power controller) CPU upgrade to system memory type, and early in 2003 to develop cutting-edge new product type constant current, constant voltage type collectively referred to as STR (may silicon-controlled thyristor power controller) the inherent brand. In 2000 to develop the motor starting device - soft starter motor new products and the inherent SMC brand available at the area of power control both at home and abroad alike. Market in 2000 and 2002 patent SSC (packaged solid-state thyratron power controller), as well as sales from the company since its inception back filter with Pulse Timer and other products in the same trade firmly occupy The largest market. Also in 2002 the development of the supply of silicon wafer characterization equipment and sub-Plasma Ion Plating with the most cutting-edge power supply devices and so on, so if the company has high-speed development.

The main purpose of this thesis is to research and develop three different kinds of battery chargers of resonant-switch converters. Starting with the zero voltage switch and the zero current switch converters, which employ the quasi-resonant converter technique, we gain the best parameters of the resonance components from the characteristic curve diagrams of these two converters. Then we design battery chargers based on these two structures and use them to experiment on lead-acid batteries.
