The paper presents three mechatronics project courses for the students of the first degree of Bologna program at the University of Maribor, Slovenia. Three courses, Project I, Project II and Project III, are assigned to the project work in the second and third study year. First course, Project I is some kind of introduction into the project work and the students are almost fully supervised by the...
A system of 1-phase semi-converter fed battery charging circuit meant for being supplied from a self-excited induction generator is analysed with extinction angle control (EAC) scheme. Several modes of operation of this scheme with continuous as well as discontinuous load current have been identified and the input and output voltage and current wave forms for each one of them have been depicted. Starting...
An interleaved PV stand-alone dc bus system, equipping with incremental conductance (IC) derived MPPT and bi-directional dc-to-dc converter (BDC), manipulated by an energy management control (EMC) is proposed. The EMC can adaptively provide interleave control for pumping energy from PV panel without intermittence and maintain well load regulation through a bi-directional dc-to-dc converter (BDC).
Design an electrical locomotive 110 V D.C. source with PFC based on the structure of two-stage switching converter. Discuss the design scheme of main circuit and control circuit. Expound the calculation method of the key parameters. The experiments indicate that the device gets good performance on output and reliability. The electric source is appropriate for electrical locomotive and the other similar...
The paper presents realization and control of a two-phase bi-directional interleaved converter for a photovoltaic (PV) system. Harmonic contents due to switching action in a dc-dc converter are reduced by the interleaving technique. A nonlinear function is used for predicting the maximum power point (MPP). A novel multi-loop control scheme is developed to achieve maximum PV power generation under...
A chronic drinking water shortage is one of the most important issues in the developing countries, and drinking water from dirty water sources causes serious damage to inhabitants health in some remote areas. The solar distillation remains the most favorable process for the supplying of water to small communities. Base on the traditional solar still, an improved hybrid photovoltaic/thermal (PVT) desalination...
In this paper, a hybrid power system supplied by a fuel cell and a lead-acid battery is realized by using the digital signal processor (DSP) TMS320LF2407 for power management and interleaved control. When the power provided from the fuel cell is higher than the load power, the extra energy may be used to charge the lead-acid battery. When the fuel cell can not provide enough energy to the load, the...
A novel bi-directional buck-boost converter used for battery charging and discharging cooperated with a three-level half bridge inverter in a UPS is proposed. The operation of charging and discharging can be controlled respectively, and the capacitor voltage balance can be achieved based on the peak current control. The operating principle and parameter design of the converter are analyzed in detail...
