A semi-dual-bridge resonant converter derived from the popular dual-bridge resonant converter (DBRC) topology is proposed in this paper for applications requiring only unidirectional power flow such as various types of DC power supplies, battery chargers in electric vehicles and dc-dc stage of different types of photovoltaic inverters. Based on the similarity of topology to the DBRC converter, the...
In the paper, to simplify the measurement and attitude control system, the simulation equipment is proposed. The soft simulation is simplified by substituting the virtual model with hardware-in-loop simulation. Meanwhile, a process transforms the three-dimension movement to two-dimension movement, and realizes simulation on uniaxial simulation equipment. A model in MATLAB/Simulink is done to compare...
An approximate method is often applied to solve the differential mass conservation equations, of which the solution by exact analytical methods is impossible. The methodology developed in this work is based on an approximate method for decoupling the gas conservation equation. With this strategy, the calculation of gas concentration and solid conversion at any time and position can be converted to...
The turbine flow capacity and thermal economy of regenerative system are the difficulty and key points for the monitoring and analysis system in Daya Bay nuclear power plant. Characteristics of flow area are used as the parameters to characterize the turbine flow capacity in monitoring system. And the quantitative analysis models of secondary loop thermal system is proposed using the theory of equivalent...
Evolution characteristics of particle pore structure not only reflect reactive process, but also intensify the complicated degree of the reaction. Variation of pore structure in coal char particles is too complex to be described only by the invariable structure parameter ?? when the random pore model (RPM) is used to describe reaction process. In this paper, the structural parameter ?? in random pore...
By continuing the control surfaces of the time-varying modifying factor analytic expression method, a new algorithm is constructed to improve the properties of the fuzzy controller obviously. The algorithm has two merits: (a) static error is erased by fuzzy method; (b) operation speed is fast. The excellent quality control and rapid response real time system can be realized together. Furthermore,...
