This paper introduced the operation principle of current mode control boost converter. The equations of two different work states were built by applying the theory of KCL and KVL. Two models working in CCM and DCM were respectively established using Matlab/Simulink and the nonlinear phenomenon of boost converter can be observed through simulation. The results of theoretical analysis are corresponded...
With the individual capacity of wind power generation system increasing, the demand for high power grid-connected converters is growing, which is usually limited by the available semiconductor technology. One solution is multiple lower power units connected in parallel. In this paper, direct parallel and interleaved parallel are analyzed and compared. Then it focuses on two parallel interleaved converters...
Intermittent phenomena are commonly observed in periodically driven switching power converters. This paper explores the intermittent chaos and subharmonics in a current-mode controlled SEPIC converter using a circuit model with intruding interference. The theoretical analysis and computer simulation are prensted, which indicate that the signal strength and frequency of the intruding interference are...
DC-DC converters are the kernel parts in the switching power supplies. There are abundant dynamical behaviors in them. In order to discover all these linear and nonlinear phenomena, it is demanded to put forward some appropriate modeling methods. This article discusses the modeling methods, which aimed at some familiar DC-DC converters under the control of voltage and current mode. They include exact...
Modulating reference current with a compensating ramp is a traditional method to stabilize the operation of the peak current-mode controlled DC/DC boost converter. In this paper, this method is applied to a PFC boost converter for gaining the stable operation target. Time-domain waveforms obtained by computer simulations are provided to illustrate the control results. Analytical investigations confirm...
