Switch unit with soft switching function and method

The invention relates to the technical field of soft switching power supplies, in particular to a switch unit with a soft switching function and a method, the switch unit comprises a main switch, a soft switch, a backboard, a power supply module, a switch module and branch load switches, and the method is characterized in that the external part is subjected to coupling operation of the main switch and the soft switch, and the internal part is driven by the switch module; according to the switch unit and the method, direct power-on and power-off of a high-power load are converted into controllable time-division and branch switch soft power-on and power-off, operation errors are prevented, and adverse effects of power-on and power-off actions on a power grid, a power distribution cabinet and other equipment are avoided. 本发明涉及软开关电源技术领域，尤其是一种具有软开关机功能的开关单元及方法，包括总开关，软开关，背板，电源模块，开关模块，各分路负载开关，该方法在于外部通过总开关及软开关的耦合操作，内部通过开关模块的驱动，将直接的大功率负载上、下电转变为可控制的分时段及分路开关的软上、下电，本发明利用本发明所提供的开关单元及方法，防止了操作失误，避免了开机、关机动作对电网、配电柜及其他设备造成的不良影响
