Switching voltage regulator (VR) modeling has numerous advantages over the conventional state average VR modeling methodology, in terms of accuracy, functionality, tuning capability, and extended applications on EMI. In previous work, switching VR modeling based on Pspice was discussed [1]. However, it is fairly accurate with simulation time limited by circuit complexity and often results in convergence...
The increasing penetration of generation power plants based on renewable energies in the electrical networks has boosted the number of systems connected to the grid. In this scenario the microgrid, providing advanced functionalities to improve the stability and operation of the network, have become very popular. In this paper a control strategy for the microgrid management is presented. The proposed...
Analysis of transient behavior is important for class E amplifier because high peak switch voltage may be imposed to the transistor in the transient response. However, transient behavior of class E amplifier due to load variation was not analyzed yet. In this paper, transient behavior of a class E amplifier due to load variation is simulated with PSPICE. As a result, it is found that a high transient...
A novel methodology for accurate and efficient static timing analysis is presented in this paper. The methodology is based on finding a frequency domain model for the gates which allows uniform treatment of the gates and interconnects. It is shown that despite the highly nonlinear overall gate model, a frequency domain model of the gate with the model parameters, gate moments, as functions of the...
A novel switched-capacitor voltage divider was proposed in the previous work. It can achieve 1kW/in3 power density, 98% efficiency and has been demonstrated in system two-stage power architecture for laptop. However, the transient performance of the voltage divider remains unclear. In this paper, the small-signal average model of the voltage divider is presented firstly. It analytically demonstrates...
