Differences Between High-Frequency and Power-Frequency X-ray Machines

The use of energy-storage components greatly reduces mains-power demands; in many cases the system can run directly from a standard supply (large power-frequency units often require a dedicated feed). At the same time, the high-voltage transformer can be made much smaller, facilitating overall miniaturization of high-power generators.
