Medical power supply

Medical power supply

High-precision medical equipment is more and more needed by the society,especial for MRI-magnetic resonance imaging – is a powerful medical technology that has revolutionised diagnosis of a very wide range of illnesses and injuries, greatly reducing or in many cases eliminating the need for exploratory surgery. It provides medical practitioners with two- and three-dimensional images, as well as high-accuracy cross-section, of internal structures an organs within a patient’s body.

In electro technology and medical diagnostic technology, state-of-the-art power semiconductors are constantly creating new ways to implement processes, to improve them, and to make them more energy efficient. Common key features of modern power semiconductors are high currents, voltages and frequencies, low losses to be dissipated, and high reliability and load cycle stability.

Improving processes and saving energy

Processes in electro technologies are very energy-intensive. The need to control high currents leads to relatively high energy losses in power electronic actuators. Reducing these losses therefore contributes directly to higher energy efficiency. At the same time, attainable process features are dependent on the features of the power semiconductors and the options for the circuit topologies.The diverse fields of application and topologies of power supplies for technology and medical uses lead to very different requirements on power semiconductors in terms of blocking voltage, forward current and switching characteristics.
