ABSTRACT:
An apparatus for switch control of the slave SPS (switching power supply) in a SPS system is provided, with minimized number of the isolation devices, to trigger OFF state of slave SPS DC output signal free from residual voltage. In addition, the inventive apparatus for controlling the slave SPS switching is implemented on the secondary side of the slave SPS only, which eliminates the difficulty and unsatisfactory adjustments associated with the PCB layout process when implementing the invention.
