“…The use of a double PI controller (named PII controller from now on) can improve the disturbance rejection and therefore the reference tracking [41], [42]. If again, the inverter from case study 1 or similar systems are controlled with a PII controller, an open-loop with two integrators and positive gain is obtained (i.e.…”

A key factor in the design of power electronic converters is the development of control systems and, in particular, the determination of their stability. Due to ease of application, the Bode criteria are currently the most commonly used stability criteria, both with regard to its classic version and to the subsequent revisions proposed in the literature. However, as these criteria have a limited range of applicability, on occasions it is necessary to resort to other universally applicable criteria such as the Nyquist criterion. Unlike Bode, the Nyquist criterion can always be applied, although its use considerably complicates the tuning of the controller. This paper proposes a new stability criterion, called Generalized Bode Criterion, which is, on the one hand, based on the Nyquist criterion, and therefore always applicable, and, on the other hand, calculated from both the Bode diagram and the 0 Hz phase of the open-loop transfer function, thus making the criterion easy to be applied. This way, the proposed criterion combines the advantages of Nyquist and Bode criteria and provides an interesting and useful tool to be applied to the controller design process. The criterion is validated by means of simulation and experimental tests made on a voltage control loop for a stand-alone PV system including a battery, a boost converter, an inverter and an ac load. The tests are also used to show the limitations of the classic Bode criterion and its revisions to correctly determine the stability of complex systems.

“…Electronic devices require AC to DC converter (rectifier) to convert AC voltage from the grid to DC voltage for the electronics and its result is low power factor (PF) and harmonic current injection into the system. Nowadays, power factor correction (PFC) converters are being widely used which can achieve high power factor (PF) and reduce the harmonics caused during AC to DC conversion (Praneeth & Williamson, 2018;Williamson, Rathore & Musavi, 2015;Nussbaumer et al, 2019;Anwar et al, 2017;Al Gabri, Fardoun & Ismail, 2015;Badawy, Sozer & De Abreu-Garcia, 2016;Memon et al, 2019aMemon et al, , 2019bMemon et al, , 2019cMemon et al, , 2019d.…”

“…This is specially visible in the work related to the construction of bridgeless SEPIC converters and its modified forms [8]- [10], where more recent contributions provide converters with a smaller number of switches. There have been a lot of research efforts related to PFC boost converters [12]- [15] and the control methods for the bridgeless boost PFC rectifier [16], [17]. Most of the Boost rectifiers are designed for operating in the continuous conduction mode which is easier to control but produces high switching losses.…”

In this paper, all operating modes of the AC-DCĆuk converter have been modeled as linear-time invariant systems where some of the modes were not only modeled but also detected for the first time. Another feature provided in this paper is that the converter can be modeled and analyzed as a switching dynamical system controlled by an external constant duty-ratio switching and the internal switchings shown to be related to the minimum among the time-derivatives of a common quadratic Lyapunov function. Some representative simulations are provided to illustrate and validate the technical results of the paper.
