“…Two control loops are mainly existing in the three-phase boost PFC rectifier control configurations: (1) Inner active and reactive current control (2) Outer DC voltage control to retain stable DC-link voltage under unbalanced and distorted voltage conditions [17,18]. It is worth noting that the PI controller is not sufficient for the inner current loop to suppress the THD, particularly 5 th and 7 th order harmonics.…”

This paper performs parameter optimization of proportional-integral (PI) and repetitive controller (RC) with a new objective function by adding two degrees of freedom for a three-phase boost power factor correction (PFC) rectifier. The main objectives are to optimize the multiple control loop parameters for total harmonics distortion (THD) reduction and dynamic performance indices improvement, including overshoot, rise time, and zero steady-state error. The control parameters of the three-phase boost PFC rectifier are optimized through a standard genetic algorithm. After obtaining the optimal PI and RC parameters values, fast Fourier transform and dynamic response analysis were performed using MATLAB. Moreover, separate evaluation functions are used to validate the optimal results in terms of THD reduction and dynamic performance indices improvement. Furthermore, the results are compared with the existing objective functions to show the proposed objective function superiority. Simulation results demonstrated that our proposed objective function outperforms existing objective functions to achieve optimal PI and RC parameters value. Finally, simulation results are validated through experimental results. The experimental setup includes a 5kW three-phase PFC rectifier with DSP TMS320F28335 prototype hardware to verify controller parameter performance.

“…Except the average dc voltage, the output voltage of a single-phase PFC converter contains double-line frequency harmonic component rooting from the pulsating input power at ac side. 19,20 If this ripple voltage passes through the voltage controller to the current loop, it will directly influence the accuracy of current reference and increase current harmonics. For this reason, the voltage controller is generally set with low bandwidth to restrain the second harmonic ripple, which instead leads to poor transient performance as the output load varies.…”

Conventionally, the dual-loop PI controllers are designed for the single-phase boost power factor correction (PFC) converters operating under continuous conduction mode (CCM), which is not available to perform rapid adaptations to plant uncertainties caused by the different operation modes and the parameter variations. In order to improve the control performance and robustness, a cascaded model-free predictive control (MFPC) scheme is proposed based on the unified ultra-local model under CCM and discontinuous conduction mode (DCM) for the single-phase boost power factor correctors. Different from the traditional sluggish PI controllers, the proposed control law is adaptive to the operation mode and sudden variations with the algebraic identification technique, thus providing high-quality line current and fast dynamic characteristic for the full power operating range. Comparative simulations and experiments with PI control scheme are provided to certificate the effectiveness of the proposed control scheme.

“…However, in this scheme, an additional load‐current sensor is required. A harmonic current feedforward solution is reported in Li et al, 16 where the proposed method extracts third harmonic current of the input current to offset the second harmonic in the voltage outer loop, thereby reducing the reference current distortion. This scheme only solves the negative impact of the second harmonic component injection, without considering the impact of the high even harmonic components of the output voltage.…”

Generally, low‐bandwidth condition of control voltage loop is used for single‐phase alternating current–direct current (AC–DC) power factor correction (PFC) converter, which eliminates the influence of the second harmonic component in the output voltage on control loop but degrades the load dynamic performance. However, the high‐bandwidth condition of voltage loop would cause multiharmonic distortions both in the input current and output voltage. Regarding this issue, this paper proposes a multidimensional harmonic current feedforward compensation control (MHCFC) scheme, to eliminate multiharmonic distortion of the PFC system using a high‐bandwidth condition of voltage loop and improve the dynamic performance as well. In the proposed scheme, the odd harmonics of the input current are extracted through multidimensional band‐pass filters and further converted into even harmonic compensation signals via the coordinate transformation, so as to offset the negative effects of the even harmonics of the output voltage. Taking boost PFC circuit as an example, a digital controlled experimental prototype is built to verify the feasibility of the proposed control scheme. The experimental results show that, compared with the traditional low‐pass filter (LPF) scheme, the proposed scheme guarantees a high‐quality input current while its load dynamic response is improved by about 70%.
