DC to DC Converters
1) Buck Converter a) Make the circuit for buck converter using the following parts: VDC (voltage source) VPULSE (voltage source) IRF150 (Swtich) R (Resistance) L (Inductance) C (Capacitance) DIN4002 (Diode) GND_SIGNAL/CAPSYM PARA ( For defining variables and their values) Double click on the parameter “PARA” and then use “new column”
option for adding the varibles and their values.
b) Simulate the circuit and get plots for capacitor current and voltages
c) Similarly get plots for inductor current and voltages
d) For getting plots for load current at different values of duty cycle use “Parametric sweep” from “Simulation parameters settings” and then put “Duty Cycle” as the parameter name. Specify its start value, end value and increment.
e) Similarly get plots for load current at different switching frequencies
2) Boost Convertera) Make the circuit for boost converter using the following parts: VDC (voltage source) VPULSE (voltage source) IRF150 (Swtich) R (Resistance) L (Inductance) C (Capacitance) DIN4002 (Diode) GND_SIGNAL/CAPSYM PARA ( For defining variables and their values) Double click on the parameter “PARA” and then use “new column”
option for adding the varibles and their values.
b) Simulate the circuit and get plots for capacitor current and output voltage.
c) Similarly get plots for inductor current and voltages
d) For getting plots for load current at different values of duty cycle use “Parametric sweep” from “Simulation parameters settings” and then put “Duty Cycle” as the parameter name. Specify its start value, end value and increment.
e) Similarly get plots for load current at different switching frequencies
3) Fly Back Convertera) Make the circuit for Fly Back converter using the following parts: VDC (voltage source) VPULSE (voltage source) IRF150 (Swtich) R (Resistance) L (Inductance) C (Capacitance) DIN4002 (Diode) XFRM_Linear ( Transformer set coupling between windings as 1) GND_SIGNAL/CAPSYM PARA ( For defining variables and their values) Double click on the parameter “PARA” and then use “new column”
option for adding the varibles and their values.
b) Simulate the circuit and get plots for output voltage and current
c) Using the parametric sweep get plots for output current at different duty cycles
