Computer-Aided Multi-Layer Design of Switch-Mode Power CircuitsSwitch-mode circuits are used as power processors, e.g. DC/DC converters, synchronous rectifiers, high-frequency resonant power amplifiers. Their efficient computer-aided design is a technical problem only partly resolved so far. This paper presents a multi-layer CAD methodology for switch-mode power circuits. It discusses several levels of modeling of switching devices. First rough design verification is feasible using ideal switch models. It gives a satisfactory first-cut design. Then full models and general-purpose tools provide more exact verification of the design. At this exact step the design procedure makes use of interactive improvement followed by automatic optimization of some quality based objective functions. The proposed methodology is shown to be especially useful for high power class-D voltage-switching resonant amplifiers, where the so far used experimental optimization is extremely cost consuming.

“…A sampled data approach has been adopted to find a discrete-time full order state-space model of a Cuk converter in [28]. In [29], a nonlinear discrete recurrence relating the state vector at the beginning of a cycle to the state vector at the end of the same cycle is used to obtain a large signal modeling of a boost converter operating in CCM and DCM. This method has some similarities with the current injected approach that is used in [30] to derive the transfer functions of the three basic converters operating in DCM at constant frequency with duty ratio control.…”

A previous article has presented the members of the asymmetrical interleaved dc/dc switching converters family as very appropriate candidates to interface between photovoltaic or fuel cell generators and their loads because of their reduced ripple and increased current processing capabilities. After a review of the main modeling methods suitable for high-order converters operating, as the asymmetrical interleaved converters (AIC) ones, in discontinuous current conduction mode a full-order averaged model has been adapted and improved to describe the dynamic behavior of AIC. The excellent agreement between the mathematical model predictions, the switched simulations and the experimental results has allowed for satisfactory design of a linear-quadratic regulator (LQR) in a fuel-cell application example, which demonstrates the usefulness of the improved control-oriented modeling approach when the switching converters operate in discontinuous conduction mode.

Abstract-Switched circuits are widely used, particularly for power electronic applications in which efficiency is important. Of these applications, the class-E amplifier has been given particular attention, since it is theoretically a 100% efficient switched circuit that has been successfully demonstrated in applications such as ballasts, converters, frequency multipliers and communication amplifiers at frequencies as high as 10GHz. However, with increasing power or frequency, nonlinearities become extremely important, for instance, in order to achieve actual class E operation and even to avoid destruction of the switching device.In this paper, a new method for determining the steady-state response of nonlinear circuits containing ideal switches is proposed. While the method is more general, the description is based on the Class E amplifier because of its inherent interest. The method is based on a time-domain Gear discretization of the circuit equations. A technique for determining the initial samples of the discretized equation of each topology is developed, based on the fact that state variables are constant during switching. Finally, assuming a periodic steady-state, a single algebraic system of nonlinear equations is obtained in which the unknowns are the samples of the control variable of the nonlinearity in the whole signal period. To validate the method described, a comparison with PSpice simulations is provided.
