This paper describes the design of special high power DC-source 110V/1kA. The emphasis was taken to the issue of the negative impact minimizing of DC source on power supply network from low-frequency interference point of view. The paper contains the simulation model of proposed DC source and simulations of two connections. The simulation results are verified by measurements on experiment.
This paper relies on the development of a model for an urban electric transportation system. This model is used to simulate the system operation both in normal and abnormal (short circuit) regimes. The simulation results are compared with the results of some theoretical studies presented in the technical literature and also with some experimental results. Unlike the theoretical idealized studies our...
Active filters are known as the best tools for harmonic mitigation as well as reactive power compensation, load balancing, voltage regulation, and voltage flicker regulation on the power lines. To introduce the operation of active filters in education, it is a good method to use a software, named SPICE. It is a good choice, because it has a high level of objects for simulation, and good presentation...
This paper is concerned with the design and simulation of a pulse width modulation (PWM) rectifier for three-phase Permanent Magnetic motor drive. Based on the mathematical model of PWM rectifier, the dual-close-loop engineering design with decoupled feed-forward control is applied in the 3-phase voltage source rectifier. The objective to be reached is to realize unity power factor at the input ac...
