(1) high "220V AC Cooling Fan" system efficiency, output voltage stability by reducing the low-voltage, high-current DC output line, the line loss is low, the system will inevitably improve efficiency. Each power required by the load generated in situ, the load and the power supply from the past to reduce the influence of the line impedance adjustment performance, but also reduce the influence of interference signals on the load, and thus "220V AC Cooling Fan" good output voltage stability.
(2) excellent EMC performance due to power more dispersed, electromagnetic interference suppression scheme is relatively easy to implement. For example, high-current and low current load isolation, large current fluctuations do not affect small current power supply, and can be used to control functions "220V AC Cooling Fan" system, so that a few large power load sharing startup, reducing the large current system impact.
