Overview of Wide Input Voltage Range Power Boards
Criteria for Selecting the Best Power Boards
Picking the right wide input voltage range power board needs careful thought. First, check the voltage range it supports. Boards that work with 85–305 VAC are great for areas with changing power grids. Choose boards with protection circuits to guard against overvoltage, undervoltage, and power surges. Features like active power factor correction (PFC) help meet rules like IEC 61000-3-2 and lower power distortion.
Efficiency is also very important. Boards using advanced parts like SiC MOSFETs or GaN HEMTs can reach over 95% efficiency at full load. Good cooling systems and heat-resistant parts make them reliable in tough conditions. Also, look for energy storage options like supercapacitors to keep devices running during short power outages.
Popular Wide Input Voltage Range Power Boards
Some boards are popular because they perform well and are flexible. For example, the Wide Input SHIM is small and changes 3–16 V input into a steady 5 V output at 2 A. Another favorite is the Mean Well LRS Series, which handles AC-DC conversion with a wide input range and high efficiency. The Vicor DCM Series has modular designs and works with input ranges from 43–154 VDC, making it good for factories and cars.
The demand for these boards is growing fast. The global high voltage power amplifiers market might grow from $1.2 billion in 2023 to $2.5 billion by 2032. This growth is due to progress in telecommunications, healthcare, and factory automation. AC-DC power supplies lead the market, holding over 62% of the share.
