HIGH-VOLTAGE PULSE MODULATOR WITH PULSE AMPLITUDE STABILISATION AND ELECTRONIC SWITCH FOR IT (VERSIONS) Russian patent published in 2008 - IPC H03K3/57 H02M3/07 

FIELD: electricity.

SUBSTANCE: invention is attributed to pulse technique, specifically to pulse power supply units and is intended for feeding high-voltage pulses to anode or control electrode to provide power supply of klystrons, particle accelerators, magnetrons, travelling-wave tubes and similar devices. Modulator (fig. 1) contains power supply unit (1), capacitors C1, C2), regulation circuit (2), voltage sensing device (VSD) (3), control circuit (CC) (4), modulating device (MD) (5), reference-voltage source (RVS) (12). Switching element (SE) of regulation circuit is made in the form of field-controlled or bipolar insulated-gate transistor (T) with resistor (R) connected with sink or in the form of field-controlled or bipolar insulated-gate T with R connected with source or in the form of field-controlled or bipolar insulated-gate T with inductance connected with sink. Furthermore CC includes comparator one of inputs of which is connected with VSD output the other output of which is connected with RVS, and output of comparator is connected with SE control input. MD is made in the form of connected in series block of switches and switch control circuit. Versions of device configuration and circuit of electronic switch for it are presented.

EFFECT: decrease of mass-dimension characteristics with reliability enhancement.
