This paper presents a single-switch, high step-up, non-isolated DC-DC converter for photovoltaic (PV) power application. The proposed converter is composed of a coupled inductor, a passive clamp circuit, a voltage multiplier cell, and a voltage lift circuit. The passive clamp circuit recovers the leakage inductance energy of the coupled inductor and limits the voltage spike on the switch. Configuration of the passive clamp and voltage multiplier circuits increases the converter voltage gain. High-voltage gain without a large duty cycle, low turn ratio of the coupled inductor, low-voltage stress on the switch and diodes, leakage inductance energy recovery, and high efficiency are the main merits of the suggested DC-DC converter. Steady-state operation of the converter in continuous conduction mode (CCM), discontinuous conduction mode (DCM), and boundary condition mode (BCM) is discussed and analyzed in detail. Then, design procedure of the proposed converter is given. The presented DC-DC converter is compared with similar topologies to verify its advantages. Moreover, theoretical efficiency of the presented converter is calculated in details. Finally, simulation and experimental measurement results of 388 V-220 W prototype of the proposed DC-DC converter at 50-kHz switching frequency are presented to verify its performance.

This paper presents a new topology of the input current continuous switch boost inverter (ICCSBI) and a perturbation observation with hysteresis comparator method. Because the traditional inverter needs to join the dead time to avoid short circuit, the dead time will cause distortion of the output current. And the traditional inverter is not suitable for photovoltaic power generation because it is a buck converter. The ICCSBI structure improves the booster circuit, which refers to the Z-source inverter. It can get higher voltage than traditional inverter. Meanwhile, the ICCSBI not only retains the advantages of the Z-source inverter but also reduces the number of passive components. In addition, the hysteresis band comparator is added to the perturbation observation method to make the system better robustness at the maximum power point of the photovoltaic system. In the photovoltaic system, to ensure the output current stable, the current control method is added to the ICCSBI. Finial, the experimental results are presented to demonstrate the new topology and control method.

Abstract:The purpose of the presented flyback converter is to equalise the voltage between the cells in a series string within a battery pack providing an active cell-balancing system. This would be an important part of a battery management system (BMS) for charging li-ion batteries in electric vehicles. The converter is based on primary side current sensing, where the conventional feedback circuit is omitted. The purpose of this converter is to improve efficiency by decreasing losses and to increase battery power density by decreasing the number of elements which constitute the power electronics; these are important factors for the future development of electric vehicle battery packs. Analysis of the circuit and the design procedure of the DC-DC flyback converter with primary current sensing is presented in this paper. Finally, several experimental converters have been built and tested to validate the authors' approach.
