Circuit producing given currents in loads from several sources - has common clamping unit limiting voltage drops in individual parallel circuits when certain value is reached

摘要

The circuit supplies equal or specified different currents to loads supplied from different sources through current transforming elements. A clamping function unit (A) limiting the voltage drops in circuit input paths (S2/R2) is connected in parallel with these paths. The paths are decoupled from each other and each contain the control path (S2) of a current transforming element (T2) and at least one negative feed-back component (R2) carrying the supply current (i2). The clamping unit is common to all current paths and limits the voltage drop when a specified value is reached.
