“…Moreover, boost type switching regulators are connected with all ports in the multiport system except port1 for independent control of each port power through the MPPT (P&O algorithm) controller [12][13][14][15]. This can be achieved by a simple strategy, in which one of the duty cycle K 1 can be updated at a time while the other duty cycles are fixed so that the source1 voltage and current can be controlled.…”

A green power revolution is essential for the country to achieve a sustainable energy base that will support the goals of economic development, energy security and environmental protection. Nowadays, Photo---Voltaic (PV) system plays a vital role in power generation systems. The paper deals with efficient simultaneous power management of solar renewable energy sources using Multiport DC-DC converter. The proposed converter reduces number of switches, controller circuit and each port can be conveniently linked to one controllable switch for proper operation of the system. Moreover, it has less components and simple in construction. All the ports are said to be connected in parallel and thus provides continuous supply of power to the load. The proposed converter is developed for simultaneous maximum power point tracking (MPPT) of PV modules at different operating conditions. A simple Perturbation and Observation (P&O) MPPT algorithm has been developed for continuous extraction of maximum power from PV panels. A single MPPT controller arrangement deals with the change in irradiation level of each port connection has been studied using Matlabsimulink environment. The specifications of the PV module have been obtained from the manufacturer datasheet (MS24250) for these analyses.

“…Therefore, many methods of overcoming these drawbacks have been proposed [6][7][8][9][10][11]. In one such method, passive auxiliary circuits of parallel type are connected to both legs of the conventional full-bridge converter to achieve the ZVS of the primary switches over the entire load range [6].…”

“…However, this technique is difficult for the design optimization of the magnetic components, due to the variation in the switching frequency resulting from the PFM operation of the converter [9,11]. In [12], an auxiliary circuit with an active switch in the converter secondary side is added, and another auxiliary circuit with a third auxiliary winding of the main transformer is suggested in [13] and [14] for the zero current switching (ZCS) of the lagging leg.…”

-This paper presents a simple high efficiency full-bridge DC-DC converter using a series resonant capacitor. The proposed converter achieves the zero voltage switching of the primary switches under a wide range of load conditions and reduces the high circulating current in the freewheeling mode using the leakage resonant inductance and the series resonant capacitor. Thus, the proposed converter overcomes the drawbacks of the conventional full-bridge DC-DC converter and improves its overall system efficiency. Its structure is simplified by using the leakage inductance of the transformer as the resonant inductance and omitting the DC output filter inductance. Also it can operate over a wide range of input voltages. In this paper, the operational principle, analysis and design example are described in detail. Finally, the experimental results from a 650W (24V/27A) prototype are demonstrated to confirm the operation, validity and features of the proposed converter.

A full-bridge secondary dual-resonant DC-DC converter using the asymmetrical pulse-width modulated (APWM) strategy is proposed in this paper. The proposed converter achieves zero-voltage switching for the power switches and zero-current switching for the rectifier diodes in the whole load range without the help of any auxiliary circuit. Given the use of the APWM strategy, a circulating current that exists in a traditional phase-shift full-bridge converter is eliminated. The voltage stress of secondary rectifier diodes in the proposed converter is also clamped to the output voltage. Thus, the existing voltage oscillation of diodes in traditional PSFB converters is eliminated. This paper presents the circuit configuration of the proposed converter and analyzes its operating principle. Experimental results of a 1 kW 385 V/48 V prototype are presented to verify the analysis results of the proposed converter.
