“…In [29], the AC bridge is derived from the push–pull DC‐to‐DC converter, whereas in this proposal is based on the half‐bridge. The advantage of using the last configuration is that the overvoltages across the bidirectional power switches during the turn‐off switching are reduced.…”

In this study, a new isolated bidirectional DC-to-three-phase AC converter for integration of renewable energy sources to the electric grid is presented. The main features of this topology are galvanic isolation, capability to control the power flow bidirectionally, soft switching, unit power factor under open-loop control and also allow step up and step down the voltage. Its operation principle is described and a modulation strategy is proposed, which allows to control the power flow according to the requirements of the load and to operate with minimum switching losses owing to the soft switching. The results revealed the feasibility of the proposal with a THD i of the AC current waveforms below 5% and the power factor above 0.98. (a) With a low-frequency transformer with an AC-DC converter, (b) With an AC-DC converter and an isolated DC-DC converter, (c) With an isolated AC-DC converter

“…These overvoltages are originated by the leakage inductances of the transformer and the parasitic inductances of the layout. By using the proposal of [29], a snubber network for each bidirectional switch is mandatory to limit these overvoltages.…”

“…Similarly, studies have been introduced where harmonic distortion and switching losses in converters are studied. Such is the case of [15], where a new bidirectional buck-boost three-phase DC-AC topology is presented, where it is possible to reduce both the harmonic distortion in the mains currents and the switching losses.…”

Modeling and Control of a Phase-Shifted Full-Bridge Converter for a LiFePO4 Battery Charger

A proper charge in an electric vehicle (EV) battery allows it to have a longer useful life and lower maintenance costs. For this purpose, the voltage and current supplied to the battery must be precisely regulated. In this article, the model of a phase-shifted full-bridge (PSFB) converter is obtained. Moreover, a dual control loop was designed to regulate the state of charge of a lithium ferrofosfate (LiFePO4) battery. The autoregressive exogenous (ARX) model is used to model the system. Once the plant model is obtained, it is controlled using a classical controller. A couple of cases are evaluated where the control parameters are modified, and the best approach is selected. From the obtained model, the controller is designed for the proposed cases. The theoretical controller response is compared with the experimental response. The results show a 94% accuracy of the model. In the same way, the result obtained from the controller is accurate in a 96% by comparing it with a simulation. Both the modeling and the control obtained experimentally resemble the results obtained theoretically. The controller manages to respond as expected in all proposed cases.
