SMPS offers a route to greater efficiency

摘要

With an estimated 2.5 billion electrical products in use in the U.S. alone, and with 400 to 500 million new power supplies sold every year, improvingrnpower supply efficiency is absolutely essential to meeting energy efficiency standards, reducing the pressure on global energy resources, and mitigating the impact of our use of technology on the environment. However, power supply implementation or selection often comes late in the overall product development process, leaving little time to optimize the design for the target application and leaving little flexibility in terms of cost of acquisition. Driven by advancing technology and both voluntary and mandatory standards, the energy efficiency of power supplies is increasing.
