| Abstract: | Tri-state Boost power factor correction(PFC) converter and its corresponding control strategy are proposed.By connecting a switch in parallel with the inductor of Boost converter,the Boost converter operated in pseudo continuous conduction mode(PCCM),which provided an additional degree of control-freedom and decoupled the control variable of the control loop.The operation principle of the tri-state Boost PFC converter was analyzed.It overcame the limitation of the output power of converter in discontinuous ... |
