Topology of non-inductive DC/DC converters with galvanic isolated circuits

Non-inductive (throttle-free) DC/DC converters are used in low-power and highly integrated electronic systems. A circuit analysis of the basic topologies of non-inductive DC/DC charge-pumped converters which perform typical DC-voltage conversions, i.e., lowering, raising and inverting, was carried out. The galvanic isolation between the input and output circuits of the converter was achieved even in the integrated version due to forming a time delay of the switches (Dead Time, DT), commuting a “flying” capacitor, which is transferring the charge to the storage capacitor and the load. A circuit of the DT driver was developed and its parameters, at which the through-current flow in the switch is prevented and the conditions of galvanic isolation of the input and output circuits are satisfied, were studied. The simulation was built with a popular Electronics Workbench software, widely used in training of specialists in radio electronics at higher educational institutions. The results of the study of the basic power characteristics of DC/DC conversion, such as output current and voltage, voltage transfer coefficient, efficiency, output equivalent resistance, were presented. The efficiency of conversion was estimated by varying the capacities of the “flying” and storage capacitors, the resistance of the switches in the closed state, and the frequency of switching. It is proved that the charge pumping method is simple and effective at low load currents (mA units), when both the voltage transfer coefficient from input to output and efficiency are high, and are approaching to “one”. However, with the increase of the load current, the voltage transfer coefficient and efficiency decrease, the output voltage ripples increase.

Basic Power Inductor Design

<p>A basic procedure for designing a power inductor is presented. Many papers and textbook chapters offer more sophisticated methods, but it is harder to find a clear outline of a basic design process. Studying and practicing a basic design process is useful for beginners to understand the fundamental tradeoffs in design and to build intuition. For more advanced work, the basic design process is useful as it avoids relying on assumptions that might not be valid with, for example, high-frequency loss effects that are ignored in the development of some more sophisticated methods, or that constrain other methods to narrow, specific cases.</p> <p>Two options are outlined: starting with a saturation constraint, and then checking the core/winding loss balance; or, starting by optimizing the core/winding loss balance, and then checking the saturation constraint.</p>

A Novel Three phase Three Wire UPQC (Unified Power Quality Conditioner) Configuration using Ten Switch Topology for linear RL loads

This paper presents a novel configuration scheme for UPQC using ten switch topology. Generally, two six-switch inverters connected back to back will form the basic power structure of three wire three phase UPQC. But there are some switches which are less utilized all the time. In order to improve the efficiency of the system, or to improve the effective utilization of the IGBTs there is a need to reduce the switch count in the system. The proposed topology uses only ten switches and gives all the results pertaining to twelve switch toplogy. The Simulation results of proposed UPQC Topology are validated through MATLAB/Simulink environment.

Research on the Driving Effect of Industrial Ecological Innovation Efficiency in the Information Age

Catch Me If You Can Game as Well as Packaging System Efficient Design Using Arduino UNO

This chapter is about a basic power-efficient object dropping game named “Catch Me If You Can,” which works on the Arduino platform. A dropping mechanism is developed using the servo motors interfaced to Arduino. The mechanism includes an object holder attached to the servomotor and a loading tube. The dropping of the objects is controlled by any wireless Bluetooth controlling device like a mobile phone or joystick and by the keypad interface installed in the design. The game is about catching the objects dropping randomly as a challenge which is controlled by the operator. The overall simulated design can be done in EasyEDA platform. The overall game can be controlled by an app which is designed by MIT App Inventor. This game can be implemented in Amusement parks, exhibitions, kid schools, and shopping malls. Besides this entertainment aspect, commercially it works as a small-scale product packaging system by involving DC motors, which are needed in moving packaging belts. This mechanism is efficient in packaging products in some specific count.
