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.

本公司在韩国把电炉电力控制装置-一般型STR升级为CPU系统内存型，与2003年初新开发的尖端产品恒电流型、恒电压型统称为STR 这一固有品牌。2000年开发电动机启动装置-电动机软启动器新产品并以SMC这一固有品牌面市，在电力控制领域受到国内外的一致好评。2000年面市并2002年取得专利的SSC(封装固态闸流功率控制器)，还有从公司创立初期销售至今的 back filter 用 Pulse Timer等产品在同行业中牢牢占据着最大的市场。2002年又开发供应硅wafer分段定性装备及Plasma Ion Plating用最尖端动力供应装置等，因此公司具备了高速发展的依据。

In recent years, cold cathode thyratron KN-22 is widely used in circuit, but here KN-22 is replaced by MOSFET. The circuit with MOSFET has stable and credible performance, it can output a pulse of -6.6～-8kV and the pulse width can be adjusted from 5ns to 10ns.

应用冷阴极闸流管KN-22作为开关线路比较广泛，但近年来我们改用MOS场效应管线路代替KN-22，该线路性能稳定可靠，输出脉冲幅度为-6.6～-8kV，脉冲宽度5～10ns可调，触发晃动小于0.5ns，触发延时30～40ns，单脉冲选出率为100%。

In the electric motor soft start question, uses the crystal thyratron intelligence module which controls by the singlechip to change the electric motor the initial firing current, the realization soft start; In the protection question, uses the singlechip to monitor the electric motor the movement, to lacks the breakdown implementation to separate the electrical machinery movement immediately, according to certain algorithm judgment electric motor whether crosses the class, like tallies has flowed the condition is the separation electrical machinery movement.

在电动机软起动问题上，采用由单片机控制的晶闸管智能模块改变电动机的起动电流，实现软起动；在保护问题上，采用单片机监视电动机的运行，对缺相故障实行立即断开电机运行，根据一定算法判断电动机是否过流，如符合过流条件即断开电机运行。
