GME Technology Co., Ltd. (Taiwan Head Office) Taiwan

GME Technology Co., Ltd. is a worldwide and leading switching power supply of standard, modified standard, custom AC / DC switching power supplies and linear power supplies from 1 / 2 watt to 80 watts. The ISO9000 approved company is headquartered in Taiwan and is dedicated to advanced research and development, supported by sophisticated manufacturing automation and in-process testing to deliver low cost, high quality power supply solutions to its clients. A switched-mode power supply, switching-mode power supply or SMPS, is an electronic power supply unit (PSU) that incorporates a switching regulator. While a linear regulator maintains the desired output voltage by dissipating excess power in a "pass" power transistor, the SMPS rapidly switches a power transistor between saturation (full on) and cutoff (completely off) with a variable duty cycle whose average is the desired output voltage. The resulting rectangular waveform is low-pass filtered with an inductor and capacitor. The main advantage of this method is greater efficiency because the switching transistor dissipates little power in the saturated state and the off state compared to the semiconducting state (active region) . Other advantages include smaller size and lighter weight (from the elimination of low frequency transformers which have a high weight) and lower heat generation from the higher efficiency.
