Enhanced Circuit Averaged Modeling of PWM DC-DC Converters

August 4, 2016 @ 2:00 pm - 3:00 pm

The development of enhanced modeling techniques for the simulation of switched-mode Pulse Width Modulated (PWM) DC-DC power converters using circuit averaging is the main focus of this seminar. The circuit averaging technique has traditionally been used to model the behavior of PWM DC-DC converters without considering important non-ideal characteristics of the switching devices. As a result, most of these existing approaches present simplified models that are ideal or linearized, and do not accurately account for the performance characteristics of the converter. This is especially problematic for low-power applications. In this context, an enhanced non-ideal behavioral circuit averaged model has been developed. The enhanced model makes the simulation of DC-DC converters both computationally efficient and accurate, thereby presenting an important tool for circuit designers. The Verilog-A based new model allows for accurate simulation of both Buck and Boost type PWM converters operating in either CCM or DCM modes while providing more than one order of magnitude speedup over the transistor-level simulation.
