This paper presents an analysis and experimental results for a feedforward control circuit suitable for applications in pulse-width modulated (PWM) buck derived converters. Line regulation can be improved using feedforward control techniques. The analysis is given for the buck converter operated in continuous conduction mode (CCM). The experimental results are performed at Vi = 17 to 42 V, V0=14 V, and the switching frequency of 100 kHz. The measured line regulation of the buck converter without negative feedback loop was less than 0.2% per 1 V of imput voltage.

Abstract
This paper presents an analysis and experimental results for a feedforward control circuit suitable for applications in pulse-width modulated (PWM) buck derived converters. Line regulation can be improved using feedforward control techniques. The analysis is given for the buck converter operated in continuous conduction mode (CCM). The experimental results are performed at Vi = 17 to 42 V, V0=14 V, and the switching frequency of 100 kHz. The measured line regulation of the buck converter without negative feedback loop was less than 0.2% per 1 V of imput voltage.
