| description | The invention belongs to the technical field of DC-DC boost converters, and discloses a high-efficiency boost converter for a small UPS and a control method of the high-efficiency boost converter, the converter is continuous in input current and small in current ripple, and the service life of a storage battery is not affected; high voltage gain is achieved, and low storage battery voltage can be boosted to high load voltage under the condition of low duty ratio; the number of power devices is small, the voltage stress is very low, low-rated-voltage power devices which are low in price and better in performance can be adopted, and the cost is low. By adopting the control method provided by the invention, the boost converter can realize soft switching in the whole load change range, further reduce on-state loss and ensure that the small UPS has relatively high operation efficiency, and the implementation method is relatively simple.
