DEVICE FOR SIMULTANEOUS POWER SUPPLY TO ELECTROPHYSICAL INSTRUMENTS WITH HIGH CONSTANT AND PULSE-FREQUENCY VOLTAGE OF SUB-MICROSECOND RANGE (VERSIONS) Russian patent published in 2012 - IPC H02J3/00 H03K3/543 

FIELD: electricity.

SUBSTANCE: device for simultaneous power supply to electrophysical instruments with high constant and pulse-frequency voltage of sub-microsecond range includes high-voltage charging unit supplying constant voltage to electrophysical instrument and high-voltage impulse generator connected parallel to electrophysical instrument, consisting of uneven number of in-series connected capacitors, two groups of charging inductance coils parallel connected to next but one capacitor, pulse transformer and start-up unit. At that, in-series connection of high-voltage charging unit and electrophysical instrument is performed through one of groups of charging inductance coils; in addition, high-voltage impulse generator includes gas-filled relays parallel connected to even capacitors, heating current stabilisation units of gas-filled relays with separating power transformers and control units of gas-filled relays. Connection of heating current stabilisation units of gas-filled relays is performed through separating power transformers, and control units of gas-filled relays are connected to start-up units through secondary windings of pulse transformers. Two more versions of the device are described.

EFFECT: increasing power efficiency, frequency band and service life of the device.
