Abstract
The invention discloses a power supply circuit shared by a main inductor. The power supply circuit comprises a plurality of circuit assemblies, the main inductor, a switch and a controller used for controlling the working state of the switch. When the switch is in a closed state, the switch, the input power supply and the main inductor form a loop to charge the main inductor; the capacitors, the primary windings of the transformers and the switches in the plurality of circuit assemblies form a plurality of loops; when the switch is in an off state, the input power supply, the main inductor, the capacitors in the plurality of circuit assemblies and the primary winding of the transformer form a plurality of loops, the input power supply and the charged main inductor are the capacitors in the plurality of circuit assemblies at the same time, the transformer induces electric energy obtained by the primary winding into the secondary winding, and electric energy output is provided. Compared with the prior art, the power supply circuit shared by the main inductors has good expansibility, can provide voltage / power output in a wider range, can achieve the electric energy conversion rate of 96% or above, and is lower in cost and better in stability in the same electric energy conversion rate.
