DEVICE FOR STABILIZING POWER VOLTAGE OF AUTOMATICS DEVICES ON VEHICLES Russian patent published in 2007 - IPC H02P9/30 

FIELD: devices for stabilizing power voltage of automatics devices on vehicles, engineering of powering voltage supplies for automatics of vehicles, possible use in automobile industry and shipbuilding for powering automatic devices of the device being transported, where usage of an accumulator is impossible or undesirable.

SUBSTANCE: in accordance to the invention, in a device, containing generator with self-excitation, rectifier, smoothing filter, load, bridged by diode in reverse direction, source of stabilized voltage, frequency detector, output of smoothing filter is connected to input of generator voltage regulator, output of which is connected to control input of first key element, output of which is made in form of transistor, coupled between output of smoothing filter of rectified voltage of generator and excitation winding of generator, bridged by diode in reverse direction, to output of smoothing filter the input of first threshold element is connected, first output of which is connected to controlling input of second key element, output element of which is made in form of normally closed relay contact, which bridges the transistor of the first key element, and second output of first threshold element is connected to first controlling input of third key element, coupled between output of smoothing filter and load, output of frequency detector is connected to input of hysteresis threshold element, output of which is connected to second control input of third key element.

EFFECT: ensured self-excitation of generator, disabled load during self-excitation, stabilization of voltage on the load without usage of accumulator.
