The driving circuit of proportional electromagnet
If you want to control the circuit,you can change duty ratio which is input to electrical signal of proportional electromagnet switch to realize controlling electric current. The more place the duty ration takes ,the faster of the controlling electric current goes through the coil of electromagnet.And the larger of the displacement . See chart 1 for the proportional electromagnet driveing circuit. In driving circuit,R1 is current limiting resistor .It conducts IRL tube.D1 is a steering diode. It provides the right voltage direction for IRL3803 tube. Diode D2 is being the protective role.It avoids over voltage destroy proportional electromagnet.Proportional electromagnet is charged directly by 24V voltage.
