Abstract:

The operation of Boost converters in discontinuous conduction mode (DCM) is suitable for many applications due to the, among other advantages, inductor volume reduction, high efficiency, paralleling, and low cost. Uses in biomedicine, nano/microelectromechanical, and higher power systems, where wide ranges of input/output voltage and a constant power load (CPL) can coexist, are well-known examples. Under extremely wide operating ranges, it is not difficult to change to a continuous conduction mode (CCM) operation, and instability, chaos, or bifurcations phenomena can occur regardless of the co

Reliability plays an important role in power supplies. For other electronic equipment, a certain failure mode, at least for a part of the total system, can often be employed without serious (critical) effects. However, for power supply no such condition can be accepted, since very high demands on its reliability must be achieved. At higher power levels, the continuous conduction mode (CCM) boost converter is preferred topology for implementation a front end with PFC.

Abstract:

The inherently different dynamics of a DC-DC converter while operating in both continuous conduction mode (CCM) and discontinuous conduction mode (DCM) necessitate an advanced controller to control the inductor current. A conventional PI controller cannot be used across both modes since it does not guarantee a smooth transition between both modes. Furthermore, in time-varying input-output voltage applications of the four-quadrant converter such as in battery charging applications, the location of the boundary between the CCM and the DCM changes dynamically, creating an uncertainty.

Boost converter is one of fundamental DC-DC converters and used to deliver electric power with boosted voltage in many electrical systems. Several control strategies have been applied to control a boost converter delivering a constant output voltage. Generally, boost converter works in two modes; one is called a Continuous Conduction Mode (CCM). Many researches use CCM model in the controller design, but they never ensure that the controller always works in CCM.

The principles and design procedures of the proposed dual-mode controller are discussed and analyzed.

Abstract The traditional PFC control adopts the PI algorithm of the double-loop structure, but the PI parameter designed at this time is aimed at the inductor current continuous mode (CCM). When the PFC enters a heavy or light load, the converter inevitably enters the inductor current discontinuous mode (DCM). If the control parameters of CCM are still used at this time, the system may become unstable and reduce load response speed. Therefore, an optimized predictive current control is proposed, which calculates the duty cycle in CCM and DCM separately in advance, and then adopts the correspon

Abstract:

A high voltage gain modified SEPIC converter is proposed in this paper. This proposed converter has many advantages i.e., high output voltage, lower voltage stress, high efficiency, voltage gain is high without any coupled inductor and transformer, continuous input current. Thus, there is no overshoot voltage at turn-off process for switches. By using single switches, the CCM mode operation can be easily controlled by this converter, so control system is simple and also wide output values is obtained only by modifying the duty cycle. This modified converter has lower components than convention

Abstract:

This paper presents a discrete-time map calculated from the nonlinear averaged model for a flyback DC-DC converter with peak current control. Traditional switched models, although accurate, are computationally expensive, limiting their practicality for rapid analysis. To address this limitation, we propose a novel discrete-time map of the flyback converter. The model achieves a simulation time reduction of over 97% compared to event-driven models while preserving high accuracy in both transient and steady-state conditions, with errors of less than 1%. Numerical simulations validate the model's
