Abstract :
Presented are the design strategies and trade-offs encountered developing a high-performance 1.5 kW switch mode power supply more compatible with the needs of small sized telecommunications centers. The proposed environmentally hardened design allows for a -40 degrees to 65 degrees standard power supply operating range, 12000 A lightning withstand capabilities, and a number of electrical performance upgrades. An effective interface is presented with pre-charge facilities allowing modular system construction designed to reduce maintenance and increase system availability.<>
