Abstract ：
临界导通模式Boost功率因素校正(PFC)电路通常采用恒定导通时间(COT)控制策略，导致开关频率的变化与输入电压、输出功率以及电感有关，轻载下过高的开关频率将影响电路的转换效率，故提出一种谷底计数频率反走(VCFF)控制策略。通过检测MOS管两端电压谷底计数，使电路轻载时工作在断续模式，从而降低开关频率以提升轻载效率。实验结果表明，相比于COT控制策略，所提控制策略能够有效提高轻载效率。输入电压为220 Vrms下，10%～50%负载时效率在0.96以上。

Abstract ：
为了解决恒定导通时间(COT)控制策略下负向谐振电流和输入滤波电容引起功率因数(PF)和总谐波失真(THD)性能变差的问题，提出一种改进变导通时间(VOT)的控制策略。通过自适应增加导通时间以抵消负向谐振电流，减小相位差，使电感平均电流在工频周期内接近正弦波，并分析其工作原理与控制过程。结合主电路设计关键参数，研制1台额定功率320 W的样机，进行COT控制策略和改进VOT控制策略的对比实验。计算机仿真和实验结果表明，改进VOT控制策略在265 V高电压输入20%负载工作时，PF值由0.726提升至0.801,THD由27.92%降低至18.4%;在40%～100%负载时满足PF>0.9、THD<15%的要求，验证所提控制策略的有效性。

Abstract ：
The traditional two-stage LED driver is usually used in the small and medium power LED drivers, resulting in some problems such as large in size and high in cost, and a large conduction loss at low voltage input, etc. To solve the above problems, a bridgeless high gain single-stage LED driver integrated by a bridgeless quadratic Boost PFC circuit and DC-DC LLC circuit was proposed, in which high voltage gain and soft switching can be realized, a set of control circuit is needed and the circuit efficiency can be improved. Aiming at the problem that the DC bus voltage variation range of the proposed single-stage circuit needs to be regulated, the APWM-PFM hybrid control strategy suitable for the proposed circuit was proposed and analyzed and the hybrid control principle and the control process were analyzed in detail. Finally, computer simulation was carried out and a 200 W experimental prototype was built up. In the range of input voltage 80 - 120 Vrms, when the duty cycle is 0. 5, the maximum voltage gain is obtained to be 6. 7, the power factor value of the prototype can be achieved to be higher than 0. 990 in all line voltage ranges, the THD can be reduced to be lower than 15% and the DC bus voltage is regulated to be under 700 V to equilibrate the line characteristics and LLC performance. Under full load condition, the prototype efficiency can reach up to 93. 20% when the input voltage is 110 Vrms. Compared with the traditional two-stage converter, the voltage gain is increased by 2. 21 times, high voltage gain and soft switching are achieved, the efficiency under low-voltage input condition is effectively improved. The proposed circuit and control method have been proved to be effective by the simulation and experimental results. © 2024 Editorial Department of Electric Machines and Control. All rights reserved.

In order to solve the problems of poor load adjustment ability and narrow output current range in traditional hysteretic current control, a fixed-ripple control strategy based on three-phase combined DC-DC Buck driver was proposed, which used the third-generation semiconductor GaN device to increase the power density of the driver. The operating characteristics of three-phase combined Buck driver and its fixed-ripple control strategy were analyzed in detail, the driver operating in continuous conduction mode (CCM) and discontinuous conduction mode (DCM) were unified mathematical modeling, small signal model and corresponding control equations were deduced, and the key parameters of the circuit were designed. Finally, a 1. 8 kW distributed multiple-phase combined Buck experimental prototype and a single Buck driver used GaN switching device were built. Computer simulation and experimental results show that: The maximum efficiency of the prototype can achieve 99. 54% at the output power of 600 W; On and off time of the switching tube can be adjusted by using the proposed control strategy adaptively, which improves the dynamic performance; 10% ~ 100% wide-range dimming and the fixed-ripple control of inductor current are realized in CCM and DCM; The constant current dimming accuracy is improved by controlling the average value of the inductor current directly, which is less than 1% . © 2023 Editorial Department of Electric Machines and Control.

Abstract ：
The deep-sea aquaculture industry will become one of the important pillars of the future marine economy. However, the application of clean energy in the new scenario needs to be strengthened for platform operation. For this kind of renewable-energy distributed-generation system, an energy storage system is essential. A bidirectional DC-DC converter is essential for distributed power generation systems. It connects a variety of renewable energy sources with energy storage cells. A high-gain bidirectional Cuk circuit with zero ripple is proposed in the paper. It is characterized by a simple structure, zero ripple, low voltage stress of semiconductor power devices, and high voltage gain. A passivity-based control with linear active disturbance rejection is proposed to solve the problems of the large steady-state error. The zero steady-state error, strong robustness, and whole-range stability have been obtained for the proposed control strategy. Finally, a simulation was carried out. A 100 W, 48 V/400 V prototype was built to verify the validity of the theoretical analysis for the proposed circuit. The improved passivity-based control strategy was verified to solve the contradiction between rapidity and overshoot. It can be realized to improve the dynamic performance of the proposed converter and achieve robust control.

Abstract ：
Aiming at the traditional communication RF amplifiers problems such as high cost and low efficiency, a single-stage AC-DC high gain step-down LED driver and its hybrid visible light communication (VLC) modulation control strategy are proposed to meet low-voltage output and VLC of LED applications. The low-ripple step-down Cuk combined switched capacitor (SC) and synchronous rectification (SR) Buck are integrated into a single-stage driver. The hybrid VLC control strategy is based on the theory of binary phase shift keying (BPSK), the LED lighting level is controlled by the average output current, and the data communication modulation is realized by the phase change of the output current ripple. The proposed circuit and hybrid control strategy are analyzed in detail, and the key parameters of the proposed circuit are designed. Finally, the computer simulation is carried out, and an input of 185~265VRMS and constant current output of 1A/25W experimental prototype is set up. The simulation and experimental results have been obtained to show that the circuit can realize high gain step-down, the functions of hybrid LED lighting control and VLC modulation, which verifies the effectiveness of the proposed driver and hybrid VLC modulation control strategy. ©2023 Chin.Soc.for Elec.Eng.
