220V Cooling Fan distributed power system design

"220V Cooling Fan" distributed power supply system is no longer a uniform supply of DC power to the system, but a system of different devices, different circuit boards, and even for the same circuit board different circuits with different power supplies. System, low frequency circuits and high-frequency circuits, small and large load current load power lines completely separated. Especially at low voltage and high current loads, "dota2雷竞技下载 " a higher voltage and then transferred to the nearby load buck DC-DC conversion module supplied to the load. Power to each circuit of the system is relatively independent, reducing high current transmission line, "dota2雷竞技下载 " the overall efficiency of the system some improvement, and the reliability and the electromagnetic compatibility problems are relatively easy to solve.
