WIDE-RANGE STABILISER Russian patent published in 2011 - IPC H02M3/156 

FIELD: electricity.

SUBSTANCE: in a stabiliser, comprising an input capacitor, a transistor, a diode, a throttle, a current sensor and an output capacitor, parallel to the input capacitor there are the following components connected in series - an upper stabilitron, a current stabiliser and a lower stabilitron, joined to a negative pole of the input capacitor, parallel to the upper stabilitron there are the following components connected - an interlocking device, connected to an upper comparator, an operational amplifier and a reference voltage divider, a sawtooth oscillator, an upper comparator and an operational amplifier, and a bridge circuit is connected in parallel to the lower stabilitron, including a transistor of an optical transistor and three resistors, and also a lower comparator. At the same time devices are used for galvanic isolation of control elements.

EFFECT: expansion of input voltage range, simplification, reduced cost, increased reliability and convenience of the stabiliser operation.
