“…On the other hand, it does not require an accurate mathematical model of a power converter, which is required in algorithms such as Model Reference Adaptive Controller (MRAC) [21] and h-infinitive controller [22]. Model predictive control (MPC) [23] and MPC based on sliding mode observer [24,25] are also well known in the literature for their satisfactory responses. However, all the techniques above mentioned require a really accurate knowledge of the converter and its parameters.…”

When working with hybrid-electric powertrain with a proton exchange membrane fuel cell (PEMFC) along with a battery pack, to increase the life of the PEMFC and avoid a drop of performance it needs to be periodically short circuited. The periodic short circuit of the PEMFC requires the DC/DC converter to be decoupled from the PEMFC. This behaviour leads the converter to undergo several start-up transients, and for an optimal energy management, the converter must reach its reference steady-state condition as quickly as possible. In this frame, this paper presents an innovative dynamic control for current mode operations of a boost DC/DC converter for managing the power exchange between the fuel cell and the battery pack, which could be easily implemented in industrial applications. With the proposed control system, the converter achieves faster step response when turned on, reducing the time required by the controlled current to reach its set point. To support theoretical considerations and simulations results, an experimental validation has been performed with a real system prototype.

“…Furthermore, the first-stage switch could be switched at a high frequency, whereas the second-stage switch must be driven at a lower frequency to avoid significant switching losses. This sort of multi-stage power conversion could reduce efficiency significantly [4].…”

This article suggests a non-isolated high step-up interleaved DC-DC topology for renewable energy applications. Two three-winding coupled-inductors along with two voltage multiplier cells are used to enhance the voltage gain significantly. One interesting aspect of this new topology is that high duty cycles are not required to achieve high voltage gains; this is done by adjusting the turn ratio of the coupled inductors. Moreover, the presented interleaved converter enjoys not only having less current stress due to the interleaving structure, but also showing 16% increase in voltage gain compared to the best similar boost topologies. Additional elements are designed for the purpose of soft switching and gain increase, which have little effect on the cost, weight and size of the proposed converter. Interestingly, the voltage stresses both on the switching devices and passive elements are much less than the output voltage. Furthermore, the coupled inductor's leakage inductance energy is recovered by employing a passive clamp circuit to minimize stresses across the semiconductors; therefore, efficiency is improved. The suggested converter is analyzed in the steady state, and a 400 W experimental setup was implemented; the outcomes verify the practicality of the proposed boost converter in accordance with the analysis.

“…Although the topology has only one main switch, switching loss and voltage stress can be reduced by selecting low resistance switching mode. A high voltage gain DC/DC cascade boost converter for fuel cell electric vehicles was presented in [12], and the output voltage is regulated by a proportional-integral (PI) controller. An improved floating interleaved boost converter was proposed in [13], which achieves a zero-ripple input current and maintains the advantages of high voltage gain and low voltage stress.…”

Direct current to direct current (DC/DC) converters are required to have higher voltage gains in some applications for electric vehicles, high-voltage level charging systems and fuel cell electric vehicles. Therefore, it is greatly important to carry out research on high voltage gain DC/DC converters. To improve the efficiency of high voltage gain DC/DC converters and solve the problems of output voltage ripple and robustness, this paper proposes a double-boost DC/DC converter. Based on the small-signal model of the proposed converter, a double closed-loop controller with voltage–current feedback and input voltage feedforward is designed. The experimental results show that the maximum efficiency of the proposed converter exceeds 95%, and the output voltage ripple factor is 0.01. Compared with the traditional boost converter and multi-phase interleaved DC/DC converter, the proposed topology has certain advantages in terms of voltage gain, device stress, number of devices, and application of control algorithms.
