This paper proposes a single inductor dual output (SIDO) DC-DC converter with an exclusive control circuit. We propose two kinds of converter: a buck-buck and a boost-boost converter. Multiple voltage outputs are controlled exclusively, using error voltage feedback. This approach requires a few additional components (a switch, a diode and a comparator), but requires no current sensors and does not depend on the value of output voltage or output current. We describe circuit topologies, operation principles and simulation results.

voltage sags represent the greatest threat to the sensitive loads of industrial consumers, the microprocessor based-loads, and any electrical sensitive components. In this paper, a special topology is proposed to mitigate deep and long duration sags by using a modified AC to AC boost converter with a new control method. A boost converter is redesigned with a single switch to produces an output voltage that is linearly proportional to the duty cycle of the switch. On the other hand, the proposed control system is based on introducing a mathematical model that relates the missing voltage to the duty cycle of the boost converter switch. The simulation results along with the system analysis are presented to confirm the effectiveness and feasibility of the proposed circuit.

To improve the disadvantage of DC-DC converter output voltage fluctuation when output current changes in wide range, a compensation circuit for improving DC-DC converter dynamic response was presented. The circuit was based on the theory of parallel or anti-parallel capacitor. A charged capacitor was paralleled when output current positive jumped. A charged capacitor was anti-paralleled when output current negative jumped. It worked when output current changed. So DC-DC converter dynamic response was improved and efficiency could be high in the same time. The simulation results proved that the effect of compensation circuit in improving the converter dynamic response and stabilizing the output voltage.

In this paper, the electromagnetic design of dual stator-winding induction generator with boost converter to raise output voltage under the minimum speed is presented. When the output voltage of power winding is very low and the output current very high, the large winding turns ratio between the control winding and power winding is proposed to reduce the current of control winding. The excited capacitor of power winding and filter inductor of control winding can be canceled. With the boost converter adjusting the out put voltage under the minimum speed, the demand of output voltage of the generator can be achieved. Design results show it is much benefit for reducing the dimension ,cost and weight of the system.

Mass commercialization of fuel cells (FC) and its usage in transportation requires that the FC technology to be competitive with regard to performance and cost, while meeting efficiency and emissions targets. Therefore, fuel cell output current ripple that may shorten FC lifespan, worsen FC efficiency and reduce the FC output capacity need to be addressed.

The Matlab/Simulink behaviour model of the improved MDIBC with novel multiplex controller and conventional MDIBC circuit are developed in the simulation studies. The proposed improved MDIBC design is then compared with the conventional MDIBC and its performance is verified.

Set Up

A novel boost converter named tri-state boost converter is introduced in this paper. According to the operation principle of the tri-state boost converter, the Euler-Lagrange model is set up. Based on the passivity-based control theory and Euler-Lagrange model, a passivity-based controller of the tri-state boost converter is designed. By damping injecting, the input current and output voltage of the tri-state boost converter can reach the desired equilibrium values rapidly. The speed of the tri-state boost converter to reach the desired equilibrium values varies when the damping values changes. The controller is simple to design and makes the tri-state boost converter having better dynamic and steady performances. The passivity-based controller proposed in the paper is proved feasible by simulation results.
