HIGH-VOLTAGE SWITCH WITH DYNAMIC LIMITATION OF ENERGY Russian patent published in 2014 - IPC H03K3/57 

FIELD: electricity.

SUBSTANCE: invention is related to the sphere of conversion equipment. High-voltage switch consists of block of electronic keys and quick-acting switch. Block of electronic keys includes compound keys containing series-connected controllable semiconductor power devices with limitation of maximum permissible voltage in closed state. Combination of parameters of semiconductor power devices and control devices included into compound keys defines maximum permissible values and characteristics of high-voltage switch. Switching of compound keys over and protection from non-accepted values of electrical action is provided due limitation of speed in changes of current (voltage) supplied to the compound keys. Protective functions of limitation are performed with usage of quick-acting switch that has required specifications to smooth drops in current (voltage).

EFFECT: possible generation of pulses regulated by shape in the load.
