“…Energies 2016, 9,83 between port 1 and port 2, L13 is the equivalent inductance between port 1 and port 3, and L23 is the equivalent inductance between port 2 and port 3. The values of L12, L13 and L23 are deduced as shown in Equation (1): Based on the equivalent model in Figure 5c, the mathematical models of active power exchanged among three energy ports can be expressed in the following equations: P P P P P P P P P (3) where ω = 2πf and f is the switching frequency.…”

“…Besides, the bidirectional DC/DC converter can be used to exchange power between the battery and the grid to satisfy the requirements of vehicle-to-grid (V2G) operation of EVs, which is shown in Figure 2 [7,8]. Bidirectional DC/DC converters can be classified into isolated converters and non-isolated converters [9,10]. Non-isolated converters usually have simple topologies and fewer components, but they face challenges in high-gain voltage conversion and galvanic isolation.…”

“…Similarly, another partially isolated multi-port DC/DC converter is proposed by using separate bidirectional half-bridge DC/DC converters for two energy sources, and high controllability is provided for power conditioning [17]. Bidirectional DC/DC converters can be classified into isolated converters and non-isolated converters [9,10]. Non-isolated converters usually have simple topologies and fewer components, but they face challenges in high-gain voltage conversion and galvanic isolation.…”

Three-port isolated (TPI) bidirectional DC/DC converters have three energy ports and offer advantages of large voltage gain, galvanic isolation ability and high power density. For this reason this kind of converters are suitable to connect different energy sources and loads in electric and hybrid vehicles. The purpose of this paper is to propose chaotic modulation and the related control scheme for TPI bidirectional DC/DC converters, in such a way that the switching harmonic peaks can be suppressed in spectrum and the conducted electromagnetic interference (EMI) is reduced. Two chaotic modulation strategies, namely the continuously chaotic modulation and the discretely chaotic modulation are presented. These two chaotic modulation strategies are applied for TPI bidirectional DC/DC converters with shifted-phase angle based control and phase-shifted PWM control. Both simulation and experiments are given to verify the validity of the proposed chaotic modulation-based control schemes.

“…Seamless mode change is realized by introducing an intermediate switching pattern. However, the PWM plus phase-shift control (PPS) control scheme, which is widely adopted in the isolated converters [31][32][33], can be employed in this non-isolated stack converter to improve the circuit performance. The duty cycle and phase shift angle of the PPS control strategy can not only balance the voltage of the high and low voltage side sources, but also regulate the power flow independently and smoothly, which eliminates the requirement of switching pattern change.…”

In this paper, a non-isolated stacked bidirectional DC-DC converter with zero-voltage-switching (ZVS) is introduced for the high step-up/step-down conversion systems. The extremely narrow turn-on and/or turn-off duty cycle existing in the conventional bidirectional buck-boost converters can be extended due to the stacked module configuration for large voltage conversion ratio applications. Furthermore, the switch voltage stress is halved because of the series connection of half bridge modules. The PWM plus phase-shift control strategy is employed, where the duty cycle is adopted to regulate the voltages between the input and output sides and the phaseshift angle is applied to achieve the power flow regulation.This decoupled control scheme can not only realize seamless bidirectional transition operation, but also achieve adaptive voltage balance for the power switches. In addition, ZVS soft-switching operation for all active switches is realized to minimize the switching losses. Finally, a prototype of 1 kW operating at 100 kHz is built and tested to demonstrate the effectiveness of the proposed converter and the control strategy.

This paper presents a bidirectional DC-DC converter suitable for low-voltage super capacitor-based electric energy storage systems. The DC-DC converter presented here consists of a full-bridge circuit and a current-fed push-pull circuit with a high frequency (HF) transformer-link. In order to reduce the device-conduction losses due to the large current of the super capacitor as well as unnecessary ringing, synchronous rectification is employed in the super capacitor-charging mode. A wide range of voltage regulation between the battery and the super capacitor can be realized by employing a Phase-Shifting (PS) Pulse Width Modulation (PWM) scheme in the full-bridge circuit for the super capacitor charging mode as well as the overlapping PWM scheme of the gate signals to the active power devices in the push-pull circuit for the super capacitor discharging mode. Essential performance of the bidirectional DC-DC converter is demonstrated with simulation and experiment results, and the practical effectiveness of the DC-DC converter is discussed.
