Control method for driving two loads by single converter

The invention belongs to the technical field of converter control, particularly relates to a control method for driving two loads by a single converter, and solves the technical problems in the background technology. When a first load is started, a second contactor is disconnected, and the converter can be quickly shut down. After shutdown, a first contactor and the second contactor are both closed, an auxiliary converter is started, the first load and a second load can be normally started, and the impact of direct input of the converter at the first load is reduced. The logic in the control method is written into the converter through programming, and the converter performs judgment and control according to the logic and automatically works. The control method does not need to consider the impact caused by sudden load switching to select a larger converter, so that the cost is reduced, and the spatial layout is saved. 本发明属于变流器控制技术领域，具体为一种单个变流器带动两个负载的控制方法，解决了背景技术中的技术问题。第一负载启动时，将第二接触器断开，变流器可快速停机。停机后，将第一接触器和第二接
