Abstract

The invention provides an inverter controlling method and device. The control method comprises the steps that each switching tube is controlled according to the control sequence of a control cycle; atthe beginning of a control cycle, firstly the first switching tube of a leading arm is controlled to be turned on, and after the first switching tube of the leading arm is turned on for a first set time, the second switching tube of a lagging arm is controlled to be turned on; when the second switching tube of the lagging arm is turned off, the second switching tube of the leading arm is controlled to be turned on, and after the second switching tube of the leading arm is turned on for the first set time, the first switching tube of the lagging arm is controlled to be turned on; when the first switching tube of the lagging arm is turned off, the control cycle ends; the turn-on time of each switching tube in the same control cycle is the same; and the turn-on time of each switching tube islonger than the first set time. According to the technical scheme provided by the invention, when each switching tube in an inverter is turned off, the voltage and current thereof are zero; and the problem that the safe operation of the inverter is affected by a hard switching phenomenon when the full-bridge inverter is controlled in the prior art is solved.

Description

technical field

[0001] The invention belongs to the technical field of inverter control, and in particular relates to an inverter control method and device. Background technique

[0002] Traditional contact power transmission technology requires wires and frequent plugging and unplugging, which limits the flexibility, safety and convenience of equipment movement, and also affects the aesthetics and cleanliness of the equipment environment; and wireless power transmission technology because of its The advantages of convenient transmission, long transmission distance, high transmission efficiency and less influence by intermediate obstacles have attracted more and more attention.

[0003] Wireless power transfer technology is realized based on the principle of electromagnetic induction. The coupling mechanism used in wireless power transfer technology is as follows: figure 1 As shown, it includes a transmitting part and a receiving part, both of which are provided with a coil...
