Abstract :
A feedforward control technique with reference voltage modulation is introduced for PWM buck converter operated in the continuous conduction mode (CCM). The reference voltage is proportional to the dc converter input voltage. A steady-state analysis is performed. Experimental results are given. The measured open-loop line voltage regulation was 1.32%/V
