Abstract
A novel control scheme for single-phase switch-mode rectifiers is presented in this letter, By utilizing the constant-switching-frequency pulsewidth m odulation scheme, the duty ratios of the switches in each switching cycle a re determined based on the available input current slopes. No current senso rs are required. The simulations and experiments show satisfactory results.
