Peculiarities of construction of electron synchrotron power supply in the case of electromagnet circuit excitation by the sinusoidal voltage

Three main basic circuits of electron synchrotron power supply systems, ensuring electromagnet resonance circuit excitation directly from power network without intermediate stages of energy storage and transformation, have been analyzed. As to the way of current regulator connection to electromagnet circuit the power supply systems are ciassafied as consecutive, parallel and combined ones. Similar controlled modules consisting of thyristor keys with parallel opposition connection and limiting electric coils are used as a regulating device in all the circuits. In the combined one the consecutive regulator is designed for current regulation in the circuit and the parallel one - for stabilization of electromagnet current phase. A circuit of power network transformation into single- phase circuit is considered. The circuit consists of power network matching transformer, monochromator electric coils and capacitors. Transformer secondary windings are connected in series and form ''irregular'' open voltage triangle (zigzag). Dagrams of network voltages and electromagnet circuit voltages in stabilization regime are given. It is shown, that the system ensures current stability in the electromagnet circuit <= 0.03%
