DC to DC Converters
  • 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.

slide6

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.

2) Boost Converter
  • 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.

slide14

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.

slide19
3) Fly Back Converter
  • 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.
