Power supply for direct current gas discharge equipment has three-phase supply with full-wave rectifier followed by inverter, transformer, second rectifier and second voltage reduction stage

摘要

A three-phase power supply (9) is connected to a full-wave rectifier (7). The resultant direct current is fed to an inverter (11) producing single-phase alternating current. This is fed to the primary (17) of a transformer (16) the secondary (18) may have the same number of windings as the primary. The secondary of the transformer is connected to a rectifier (19) followed by a direct current voltage reduction circuit (3) connected to the load (5). The circuit may be used for igniting plasma processes.
