Abstract
A novel feedforward control technique for reducing output harmonics and deviations in AC/DC switchmode power supplies is presented. To achieve this, an algorithm that computes the exact switching function based on input voltage DC and harmonic components is derived, and its implementation using pulse width modulation is discussed. For verification results from an experimental one-quadrant switch-mode magnet power supply are provided
