Abstract

The invention relates to a rectification power supply. The rectification power supply comprises an input power supply, a soft start circuit, a rectifying circuit, an output contactor KM03 and a control circuit; the output end of the input power supply is electrically connected with the soft start circuit; the soft start circuit is electrically connected with the rectifying circuit; the rectifyingcircuit is electrically connected with the output contactor KM03; one end of the control circuit is electrically connected with the soft start circuit; the other end of the control circuit is electrically connected with the output contactor KM03; and the output contactor KM03 is also connected with external equipment through a capacitor. The invention further discloses a novel radar power distribution system control device and strategy. By means of the rectification power supply, the novel radar power distribution system control device and strategy in the invention, oscillation can be suppressed in the input voltage range of an array DC / DC converter; and the problem of loss, even failure, due to the fact that the input-end voltage of the array DC / DC converter forms oscillation by long-wiretransmission can be effectively solved.
