The switching mode power supply is a device which obtains direct output voltage controlled by filters after rectifying ac commercial voltage to dc voltage and converting to spherical waveform using power semiconductor elements as switches.
It controls the power using the switching processor of the semiconductors and has better efficiency, durability, smaller scale, lighter weight, and stability than the linear power devices.
However, it should be considered that circuits which supplement surge and noise due to switching and prevent power losses due to switching and inductor by converting the switching frequency to high frequency.
The product is used as power supply in industries including appliances, OA devices, communication devices and industrial devices.
The company’s factory in China (Yeongseong Geumwon Electronics in Yeongseong City, Shandong Province) has the system which produces SMPS and is supplying 100 W and 200 W PSU to Panasonic Japan.
The factory is equipped with production facilities and quality systems for SMD, AUTOINSERT, AUTOSOLDER, AGING, and AUTOTESTER and produces OEM products.
