Method and device for controlling start of switching rectifier, and storage medium

A device for controlling start of a switching rectifier, comprising:

• a memory storing processor-executable instructions;
• and
• a processor arranged to execute the stored processor-executable instructions to perform steps of:
• acquiring an external environmental parameter of a switching rectifier and a power supply characteristic parameter of an object to be powered;
• establishing a voltage start strategy and/or a current start strategy according to the external environmental parameter and the power supply characteristic parameter;
• and
• controlling a voltage and/or a current of the switching rectifier to start to a full-load voltage and/or a full-load current according to the voltage start strategy and/or the current start strategy,
• wherein the voltage start strategy comprises:
• determining at least one intermediate voltage between an initial voltage and a full-load voltage of the switching rectifier according to the external environmental parameter and the power supply characteristic parameter, obtaining voltage boost sections using the initial voltage and the full-load voltage as endpoints and using the at least one intermediate voltage as sectioning point(s), determining a voltage boost duration of each of the voltage boost sections by making a first voltage boost section proximate to the initial voltage to have a voltage boost speed larger than a voltage boost speed of a second voltage boost section proximate to the full-load voltage, and boosting the voltage of the switching rectifier in sequence according to determined voltage boost durations.
