| Abstract |
This paper describes the design issues of a very special power supply. The target is to charge a big set of capacitors (0.5F) at a relatively high voltage (340V) .fi·om· a 24V (20-32V) battery in a limited period of time. Such amount of energy (29kJ) is used in a X-ray portable equipment for medical applications. For this capacitor charging power supply (CCPS), several topological configurations, control
methods and devices are discussed from the point of view of size, cost and reliability. The variations of the output power, switching frequency and duty cycle, produced by the evolution of the output voltage are the main constraints of this design. Experimental results are included in the paper. |
