“…(2) Fuzzy LADRC controllers can estimate and compensate for load disturbance in real time. Therefore, compared with the PI controller and references [6,11,16,18,24], the control strategy in this paper can effectively reduce the total harmonic distortion rate of input current when the load changes and the optimal value is 1.66%. (3) The limitation of the method proposed in this paper is that the fuzzy controller needs a higher experience.…”

“…This method can better track the step changes of current and voltage and has stronger robustness [15]. Ruan et al [16,17] adopted a prediction algorithm with a faster response speed for totem pole PFC, which also considered the influence of parameter disturbance on the system, which significantly improved the anti-interference ability. For further filtering, Lv et al [18] designed a PR controller to compensate for the harmonic components of the duty cycle predictive control, and added a notch filter structure to the voltage loop to improve the harmonic distortion of the input current.…”

“…(2) Model information is thoroughly used in designing the Fuzzy LADRC controller, which eliminates the defects of traditional model-free information in the design of the LADRC controller. (3) Only one fuzzy control variable is used in the design of the Fuzzy LADRC controller, which reduces the difficulty of application and the dependence on fuzzy rules; (4) Compared with the literature [6,11,16,18,24], the THD of the method proposed in this paper is lower. Finally, it is proved by simulation and experiment that the proposed method can effectively shorten the system's response time, reduce the current harmonic distortion rate, and improve the system's robustness.…”

Aiming at the problems of output voltage fluctuation and current total harmonic distortion (THD) in the front stage totem-pole bridgeless PFC of two-stage V2G (Vehicle to Grid) vehicle-mounted bi-directional converter, a fuzzy linear active disturbance rejection control strategy for V2G front-stage AC-DC power conversion system is proposed. Firstly, the topological working mode of the totem-pole bridgeless PFC is analyzed, and the mathematical model is established. Combined with the system model and the linear active disturbance rejection theory, a double closed-loop controller is designed with the second-order linear active disturbance rejection control as the voltage outer loop and PI control as the current inner loop. The controller can realize self-adaptive tuning of the proportional gain coefficient of the active disturbance rejection controller through fuzzy reasoning and realize self-adaptive control. Simulation and experimental results show that this method can better solve the problems of slow system response and high total harmonic distortion rate of input current and effectively improve the system's robustness.

“…In recent years, several voltage balancing methods of the cascaded multilevel converter have been proposed (Han et al , 2019; Kankanala, et al , 2021; Chen et al , 2020). One of the directions is to adjust the duty cycle for each H-bridge by the PI controller with a corresponding control strategy (Moosavi et al , 2014; Villanueva et al , 2009; Ruan et al , 2019). These methods that expand to each H-bridge module are simple and easy relatively.…”

Purpose The purpose of this paper is to propose a DC-port voltage balance strategy realizing it by logic combination modulation (LCM). This voltage balance strategy is brief and high efficient, which can be used in many power electronic devices adopting the cascaded H-bridge rectifier (CHBR) such as power electronic transformer (PET). Design/methodology/approach The CHBR is typically as a core component in the power electronic devices to implement the voltage or current conversion. The modulation method presented here is aiming to solve the voltage imbalance problem occurred in the CHBR with more stable work station and higher reliability in ordinary operating conditions. In particular, by changing the switch states smoothly and quickly, the DC-port voltage can be controlled as the ideal value even one of the modules in CHBR is facing the load-removed problem. Findings By using the voltage balance strategy of LCM, the problem of voltage imbalance occurring in three-phase cascaded rectifiers has been solved properly. With the lower modulation depth, the efficiency of the strategy is shown to be better and stronger. The strategy can work reliably and quickly no matter facing the problem as load-removed change or the ordinary operating conditions. Research limitations/implications The limitation of the proposed DC-port voltage balance strategy is calculated and proved, in a three-module CHBR, the LCM could balance the DC-port voltage while one module facing the load-removed situation under 0.83 modulation depth. Originality/value This paper provides a useful and particular voltage balance strategy which can be used in the topology of three-phase cascaded rectifier. The value of the strategy is that a brief and reliable voltage balance method in the power electronic devices can be achieved. What is more, facing the problem, such as load-removed, in outport, the strategy can response quickly with no switch jump and switch frequency rising.
