Short Description About Switching Mode Power Supply Market
A switched-mode power supply (switching-mode power supply, switch-mode power supply, switched power supply, SMPS, or switcher) is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently. Like other power supplies, an SMPS transfers power from a DC or AC source (often mains power) to DC loads, such as a personal computer, while converting voltage and current characteristics.
Unlike a linear power supply, the pass transistor of a switching-mode supply continually switches between low-dissipation, full-on and full-off states, and spends very little time in the high dissipation transitions, which minimizes wasted energy. Ideally, a switched-mode power supply dissipates no power. Voltage regulation is achieved by varying the ratio of on-to-off time. In contrast, a linear power supply regulates the output voltage by continually dissipating power in the pass transistor. This higher power conversion efficiency is an important advantage of a switched-mode power supply. Switched-mode power supplies July also be substantially smaller and lighter than a linear supply due to the smaller transformer size and weight.
In application, Switching Mode Power Supply downstream is wide and recently Switching Mode Power Supply has acquired increasing significance in various fields of LED industry, medical equipment, mobile phone chargers, automobiles, consumer electronics and others. Globally, the Switching Mode Power Supply market is mainly driven by growing demand for Consumer Electronics which accounts for nearly 52% of total downstream consumption of Switching Mode Power Supply.
