STABLE CURRENT SOURCE Russian patent published in 2014 - IPC H03M1/66 H02M7/53 H03C3/14 

FIELD: electricity.

SUBSTANCE: stable current source includes in-series connected filter, transformer with an interrupting transformer connected to primary winding and a rectifying diode in secondary winding, after which a low-pass filter with a measuring shunt in an output current circuit is installed, the measurement outputs of which are connected to a voltage-to-frequency converter, the output frequency of which is supplied through a galvanic isolation element to the input of a frequency-pulse modulator controlling the switch frequency of the interrupting transistor.

EFFECT: providing long-term stability of output parameters at operation immediately for load in a wide temperature range in ionising emission fields.
