Hysteresis Controller Using MOSFET Gate Driver Circuit

The main objective of this work is to protect the d.c motor in term to flow a heavy current more than the rated current of the motor. We have achieved this objective by using hysteresis current controller. The d.c machine was rated as 2.5amp,.75hp, 1500 rpm, 250v d.c shunt wound. We already had power converter performances also converter. So we simulated in PSIM software with load conditions. Successfully we fabricated the MOSFET gate driver circuit, current controller circuit and tested with the motor running under load.
