COMPENSATION FOR SHIFT IN EXCITATION CIRCUITS Russian patent published in 2016 - IPC H05B37/02 

FIELD: electricity.

SUBSTANCE: invention refers to schemes for excitation of electric loads. Result is achieved by fact that on non-inverting input of amplification unit can be supplied with bias voltage selected to exceed expected in worst case positive shift of DAC. Feedback from output of amplification unit may be sent to processor. Processor can be connected to excite DAC.

EFFECT: compensation for shift in DAC and other components of circuits used for excitation of electric loads.
