After completing this chapter, students should be able to do the following:
• Model BJTs, MOSFETs, and IGBTs in SPICE and specify their model parameters.
• Model PWM control in SPICE and as a hierarchy block.
• Perform transient analysis of DC–DC converters.
• Evaluate the performance of DC–DC converters.
• Perform worst-case analysis of diode rectifiers for parametric variations of model parameters and tolerances.
In a DC–DC converter, both input and output voltages are DC. It uses a power semiconductor device as a switch to turn on and off the DC supply to the load. The switching action can be implemented by a BJT, a MOSFET, or an IGBT. A DC–DC converter with only one switch is often known as ...
