Voltage (current) sensors with advanced temporal and temperature stability performance

The article considers the structures of (current) voltage sensors (VS) on the basis of integrating self-oscillating sweep converter with amplitude-frequency-width-pulse modulation with advanced temporal and temperature stability performance. The time-diagrams explaining the work schemes and basic analytic relationships are given. Schemes on the basis of transformer and optoelectronic elements for potential division of input-output of VS is given, optoelectronic VS for control systems of intermediate accuracy with temperature drift about 10-20 mcV/ °C and improved noise proof is considered.
