SHAPER OF ENERGY PULSES USING METAL OXIDE VOLTAGE-VARIABLE RESISTORS Russian patent published in 2013 - IPC H03K17/08 

FIELD: electricity.

SUBSTANCE: shaper includes pulse electric energy accumulators: inductance and/or a charged capacitor, at least one fully controlled quick-acting key with a parallel protective chain that restricts voltage at activation of a quick-acting key, in series with the quick-acting key(s) there installed is at least one locking key that is able to lock or pass load current, a controller connected to control chains of keys through the corresponding control devices. The protective chain of the quick-acting key(s) includes at least one metal oxide voltage-variable resistor (VVR), thus forming a pulse limiter of load current flowing either through the quick-acting key, or through VVR. In the load current chain there installed is a sensor of an electric mode and connected to a control controlling the load current on low or high frequency.

EFFECT: development of an energy shaper for the purpose of providing a powerful current pulse capable of reducing switching bursts and resonant current oscillations in load, improving operating reliability of keys and other devices physically connected to that energy shaper, and the specified limitation of load current pulse.
