“…For example, charge-coupled device (CCD) image sensors introduce nonlinear distortions when excessive light intensity causes saturation [1], [2]. Memoryless nonlinear distortions also appear in the areas of power electronics [3] and radiometric photography [4], [5]. In some cases, nonlinearity is introduced deliberately in order to increase the possible dynamic range of the signal while avoiding amplitude clipping, or damage to the ADC [6].…”

Abstract-We study a sampling setup where a continuous-time signal is mapped by a memoryless, invertible and nonlinear transformation, and then sampled in a nonideal manner. Such scenarios appear, for example, in acquisition systems where a sensor introduces static nonlinearity, before the signal is sampled by a practical analog-to-digital converter. We develop the theory and a concrete algorithm to perfectly recover a signal within a subspace, from its nonlinear and nonideal samples. Three alternative formulations of the algorithm are described that provide different insights into the structure of the solution: A series of oblique projections, approximated projections onto convex sets, and quasi-Newton iterations. Using classical analysis techniques of descent-based methods, and recent results on frame perturbation theory, we prove convergence of our algorithm to the true input signal. We demonstrate our method by simulations, and explain the applicability of our theory to Wiener-Hammerstein analog-to-digital hybrid systems.

“…The associated discrete circuit (ADC) modeling approach extend the companion modeling approach to power electronic switches. The ADC approach represents a power electronic switch with a current source in parallel with a conductance G S (Figure 3) [31][32][33][34][35]. In this approach, the conductance G S is fixed irrespective of the switch ON/OFF state.…”

A High Performance Real-Time Simulator for Controllers Hardware-in-the-Loop Testing

This paper presents a high performance real-time simulator for power electronic systems applications and primarily intended for controller hardware-in-the-loop (CHIL) testing. The novelty of the proposed simulator resides in the massively parallel hardware architecture that efficiently exploits fine-grained parallelism without imposing severe communication overhead time that can limit the performance. The simulator enables the use of a nanosecond range simulation timestep to simulate power electronic systems. Through the use of this nanosecond range simulation timestep, the simulator minimizes the error arising from the intersimulation timestep switching phenomenon associated with CHIL. The proposed hardware architecture is realized based on the FPGA technology. The simulator is tested and its CHIL capability verified based on the closed-loop testing of a robust multivariable servomechanism controller for autonomous operation of a distributed generation unit.

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.
