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