PSPICE and MATLAB/SIMULINK

Students will use scopes, power supplies, loads, function generators, multimeters, etc., for the project that involves: Inductor fabrication; Circuit board construction; Debug and testing.

Contributes toward the Electrical Engineering Topics Courses and Major Design experience.

Teach students hands-on technique such as how to solder the circuit components and use scopes, multimeters, power supplies, etc. For given specifications, students will calculate the circuit parameters, such as resistance, capacitance, inductance, MOSFET and diode requirements. Design and wind an inductor. Layout the switching circuit, PWM circuit chip, driver, dynamic compensator on a circuit board. Low noise construction methods are taught. Teach students how to debug a circuit to make the circuit to meet the specifications. Test the circuit.
