REDUNDANT SOURCE OF CURRENT Russian patent published in 2014 - IPC H03M1/36 

FIELD: electricity.

SUBSTANCE: invention contains in ACS structure resonance probes (thermal resistance probes, potentiometric pickups for actuator feedback), which require flow of permanent stable current in order to collect data from them; as a rule probes are connected in series and they require maintenance of stable current at load change and degradation of semiconductor parameters with time due to temperature change and accumulation of dose changes, and in result of such changes operation of transistors is violated and value of output current is changed. To this end the claimed device contains three identical converters of input power to output stable current; output currents of converters through cut-off unit are delivered to balancing unit, from output of the balancing unit through ballast reference resistor they come to load; outputs of the converters are also connected to control and monitoring unit by control outputs to cut-off unit and by control outputs to auxiliary power supply source; output signal comes to voltage-to-frequency converter, which control output through galvanic decoupling element to chopper transistor control module.

EFFECT: operating in wide range of temperatures in fields of ionising radiation, backing up, code control of output current and radiation resistance with time of operation at change in wide range of ambient temperatures, occurrence of fatal and parametric failures of certain elements of the source and at change of load in conditions of ionising radiation.
