摘要：
The purpose of this paper is to present a influences of parameter deviations on operation of a novel current sensorless AC-DC converter are discussed. The off time is calculated based on the equations of each operating state for boundary current control mode. The relationship among the THD, power factor and efficiency, and circuit parameter errors are discussed. When the circuit parameter varies from designed parameters, the predicted off-time can also be deviated from the optimum value. The characteristics of sensorless ac-dc converter won't change a lot when an error occurs between the main circuit and the designed parameters of the inductor.
