In this paper, implication (IMP) operations are demonstrated in a circuit with two SiOx-based memristors and a CMOS transistor. Specifically, a circuit with two one-diode and one-resistor (1D1R) memory elements and a transistor are designed to perform the IMP operations. A circuit consisting of a $4 \times 4$ crossbar 1D1R memristor array together with selection transistors is proposed and used...
The charge-trapping characteristics and trap levels of SiOx-based (TaN/SiO2/n++ Si-substrate) resistive switching memory (RS) have been investigated. Multilevel operation under compliance current control is demonstrated and current transport behavior is analyzed using the normalized conductance of low resistive state (LRS) and high resistive state (HRS). Temperature dependence of I-V characteristics...
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...
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...
Intermittency are commonly observed by practicing power supply engineers in their design workbenches. It shows to be a symmetrical period-doubling bifurcation in time domain with fixed long intermittent period. Sometimes it is called "breathing". Such kind of operation mode is usually undesired and can be avoided by means of screen technique or modifying the circuit parameters. This paper...
