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.

Passivity Based Control

A new Cuk converter with high step-down ratio was proposed. The operating principle and operating mode of the new Cuk converter were analyzed in detail and the EL model of the new Cuk converter was established. Based on passivity-based control theory, a passivity-based controller of the new Cuk converter was designed by the method called damping injection. The controller can enable the new Cuk converter achieve good dynamic and static performance and robustness to the load. Compared with Buck converters, the new Cuk converter has a higher step-down capability and a smaller ripple of the input current. Simulation results show that the new Cuk converter is feasible.

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.

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.

Euler-Lagrange (Euler-Lagrange, EL) mathematical model was established according to the topology of TNPC (T-type Neutral Point Clamped) PV grid-connected inverter. Based on the mathematical models and passivity-based control theory, the approach called injecting damping was adopted to design the passivity-based controller of the inverter. The passivity-based controller can decoupled-qaxis current at AC side of the grid and achieve unity power factor, the total harmonic distortion of grid-connected current is low, and the passivity-based controller also make the inverter have good dynamic and static performances. Simulation results show that the designed passive controller of TNPC PV grid-connected inverter is feasible.

This paper derives bifurcation and chaos phenomena for the Boost converter under current-mode control. The precise discrete iterative mode is compiled in M file of MATLAB to obtain the bifurcation diagram, the Poincare mapping, the discrete value of output voltage and inductor current; The piecewise smooth switch model is built in Simulink of MATLAB to obtain the phase diagram and the time-domain chart. On the basis of two models, the bifurcation phenomena under variation of a range of circuit parameters including load resistance, have been investigated. Two kinds of model simulation results had the better consistency, which were proved the existence of bifurcation and chaos phenomena in the current-mode Boost converter.

This paper deals with analysis of the four phase interleaved DC-DC converter for higher power application. The interleaved topology is widely used due to  its advantage as lower input current ripple which means volume reduction of the input capacitor. The current ripple equation of an input current for the boost operation mode and the ripple current in the individual phase of the interleaved converter using uncoupled inductor are shown. The theoretical equations are supplemented by the simulation results using the Spice simulator and by measurement on the interleaved converter.

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. In this paper, an improved multi-device interleaved boost converter (MDIBC) with novel multiplex controller topology is designed to further reduce the input current and output voltage ripples, without increasing the number of MDIBC switching devices. 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.
