Kinki Roentgen Industrial is a manufacturer of X-ray apparatus. Here I introduce the details of X-ray generator (core part of X-ray device), of which in-house development is one of the strongest ...points of our company. Insulation and heat-release techniques are important for designing the generators, because the high voltage (∼100 kV) for generating X-rays and the low conversion efficiency (∼1%) lead to considerable heat-load on an X-ray tube. This paper describes also the grounding method and recent developments in high-voltage power supply.
