1results about How to "Small current ripple" patented technology

The application belongs to the technical field of inverters, and discloses a low-ripple soft-switching boost inverter and application thereof. The low-ripple soft-switching boost inverter is obtained by multiplexing the upper tube of a traditional two-phase buck / boost converter and the lower tube of a full-bridge inverter and adding an auxiliary inductor. The inverter can realize soft switching, has high conversion efficiency, low current ripple and low input inductor current stress. In addition, the input current ripple frequency is increased to twice the switching frequency, the size of the required filter device is reduced, and the system cost is reduced.
