High-Voltage Multiphase Semiconductor Converters With Reduced Energy Accumulation for Gas-Discharge Installations

Abstract

A new concept has been developed for constructing of the high-voltage multiphase semiconductor converters with reduced energy storage for gas-discharge installations. The concept is developed on the basis of the creation of parallel-connected synchronous symmetric non-phase semiconductor structures with a reduced accumulation of energy in the output circuits. This approach allows the creation of converters which realize without the use of energy-intensive filters both low level of output voltage ripples and non-oscillatory pulse current change at low multiplicity and a non-current pause during the impulse decrease of the load
