This paper examines a high-power-factor boost rectifier where the peak switch current is clamped at a constant value during the input voltage line cycle. Optimum parameter values are derived to minimize the harmonic distortion in the input current. Advantages of the clamped-current control include overall simplicity, relatively low inductive energy storage and component stresses, and a fixed operating frequency. Results are experimentally verified on a 1.3 kW prototype featuring high efficiency and high power factor over a wide load range
