The Switching Power Supply (SPS) market represents the vast, foundational sector of power electronics responsible for efficiently converting raw electrical energy into the stable, regulated power required by virtually all modern electronic devices and systems. SPS units, also known as Switch Mode Power Supplies (SMPS), utilize switching components (like power transistors) operating at high frequencies to regulate power output with much greater efficiency, lower weight, and reduced size compared to traditional Linear Power Supplies (LPS). Power supply units are broadly classified by their function into LPS, SPS, and Uninterruptible Power System (UPS) power supplies. SPS is the dominant architecture due to its superior performance metrics.
