| Abstract: | In this paper,the most widely applicable power factor correction circuit-BOOST power factor correction circuit with average current control mode is presented.Considering response speed of the current loop much faster than the voltage loop,the simplified small signal models for both the current loop and the voltage loop of the circuit are derived respectively.Design principles for feedback compensations are discussed,in which loop bandwidth,noise suppress,ripple reducation and stability are liken into account as targets or constrains. Correspondent optimal mathematical modelS are provided with an example optimal design for verification |
