This paper deals with the use of the integrated circuit electromagnetic model (ICEM) to analyze, predict, and optimize auto compatibility and electromagnetic emission at PCB level. ICEM is currently under standardization process (IEC62014-3). The basic ICEM architecture is composed of a power distribution network model and an internal current source modeling digital activity. Such an approach enables...
Mathematical equations are possible to simulate with various electronic circuits. Inductors and capacitors intrinsically are capable of integrating and differentiating, and active components alone can realize such algebraic operations as addition and multiplication. In this work, linear differential equations are shown to be implemented with three active components, namely operational amplifiers(Opamp),...
This paper presents the theoretical analysis, design and simulation of a single phase single stage boost dc-ac converter powered from PV array. The main attribute of the boost inverter topology is the fact that it generates an ac output voltage larger than the dc input one, depending on the instantaneous duty cycle. This paper proposes an accurate solar panel simulation to incorporate the temperature...
This article presents a 3rd order current-mode quadrature oscillator using current controlled current conveyor transconductance amplifiers (CCCCTAs) as active elements. The proposed circuit is realized from a non-inverting lossless integrator and an inverting second-order lowpass filter. The oscillation condition and oscillation frequency can be electronically/orthogonally controlled via input bias...
A new electronically tunable single-element-controlled current-mode quadrature oscillator circuit using current differencing transconductance amplifiers (CDTAs) is presented. The proposed oscillator is consisted of two CDTAs, two grounded capacitors and one grounded resistor, which is beneficial to monolithic integrated circuit implementation. The oscillation condition and oscillation frequency of...
DC injection is a critical issue in the distributed generation systems according to IEEE Std. 1547-2003. Unfortunately, few literatures discuss this problem. In this paper, a novel control strategy is proposed to achieve zero steady-state DC injection. The proposed idea stems from a well-known fact that a capacitor can block DC component naturally. Generally, this capacitor should be large enough...
A double two-phase permanent magnet motor (DTPPM) system is proposed. It is shown that by connecting the neutral lines of a pair of two-phase machines, only four switches need to be used for each machine and the two machines share one set capacitors. This paper develops the mathematical model of this system and establishes the simulation model accordingly. Simulation results are given to demonstrate...
A systematic 3D electromagnetic (EM) analysis of metal-insulator-metal (MIM)-capacitors with up to four feedstrips has been performed to investigate the electrical effects of feed widths and positions. Based on this analysis, an efficient approximate computer-aided design (CAD) model of MIM-capacitor N-ports has been developed which is an extension and generalization of a recently published two-port...
