Abstract :
This paper presents a digital repetitive learning control scheme to realize quick response of output voltage for a medical-use X-ray power generator incorporating a converter fed by a phase-shifted PWM IGBT inverter which makes the most of high-frequency high-voltage transformer parasitic resonance. The effectiveness of the digital control scheme for this sort of X-ray power generator is confirmed through simulation analysis and experimental results
