Hysteresis Constant Current with Inductor

00:57:28

This circuit is design with single supply comparator & opamp circuit in mind. 

Relay is used to induce delay so that Everycircuit can start the simulation with zero initial voltage/current. Without this delay, Everycircuit tends to report no solution. 

Upper opamp served as single supply hysteresis comparator. Voltage supply at left of this opamp serve as control input to adjust output current. 

Lower opamp serve as single supply non inverting amplifier to magnify current to larger voltage for comparison purpose. 

This circuit should be regard as ON/OFF Close Loop Control (CLC) Current Regulating circuit.
