Summary In grid‐connected (GC) photovoltaic (PV) system with a three‐phase voltage source inverter (VSI), one major requirement is that the DC‐side voltage should be greater than the inverter AC‐side voltage. In many PV installations, this is difficult to attain without an additional DC‐DC converter. For such scenarios, a three‐phase differential boost inverter, where input DC voltage can be less than AC‐side voltage, is a promising configuration. For GC PV systems integrated with such power electronic switching converters, the power quality control also plays a significant importance. In this paper, a novel power quality control technique for such a GC PV system based on three‐phase differential boost inverter has been proposed and evaluated. The proposed control system consists of three subsystem level control loops: (1) a novel control unit for reference voltage generation required for power quality improvement, (2) a double‐loop control strategy with plug‐in–type repetitive Proportional‐Integral (PI) control for outer loop and feedback linearizing control for inner loop meant for tracking of boost inverter output reference voltages, and (3) another bidirectional DC‐DC converter controller for battery operation. The performance of the proposed control algorithms has been tested under various scenarios, ie, power management, transition between GC to stand‐alone (SA) modes and vice versa, and grid current compensation under unbalanced load, nonlinear load, and unbalanced and distorted grid voltage conditions. Extensive simulation and experimental results are reported for validating the proposed control technique.

“…In order to alleviate the drawbacks of the two-stage FC power conditioning system, a FC energy system with single power conversion stage is proposed in [12]. The topology of the single-stage three-phase boost inverter has also been discussed and presented in a couple of papers [13]- [17]. However, none of them is related with a three-phase FC system.…”

A conventional low-voltage unregulated fuel cell (FC) system requires a two-stage converter in order to generate AC power for typical loads or grid connection. In this paper, a threephase boost inverter topology that achieves both boosting and inversion functions in a single-stage is used as a building block to develop a three-phase FC-based energy system which offers high conversion efficiency, low-cost and compactness. Additionally, the proposed FC system incorporates a back-up unit with battery storage to support the slow dynamics of the FC. The three-phase output voltage of the boost inverter is voltage-mode controlled and the back-up unit is current-mode controlled. Analysis, simulation and experimental results from a laboratory prototype are presented to confirm the operational performance of the proposed system.

In this paper, a three-phase boost-inverter topology is used to condition a typical low output voltage fuel cell (FC) as a stand-alone power supply. The key benefits of the proposed power supply include ability to deliver both the boosting and inversion functions in a single stage, compactness, and low cost. Additionally, the power supply incorporates a battery storage unit through a bidirectional converter to support the slow dynamics of the FC and simultaneously protect the FC as it acts as a filter for the low-frequency harmonics. The three-phase output voltage of the boost-inverter is voltage-mode controlled and the battery unit is current-mode controlled. Analysis, simulation, and experimental results taken from a 1-kW laboratory prototype three-phase boostinverter operating at 20 kHz and bidirectional converter with two 12 V-24 Ah lead acid batteries are presented to confirm the operational performance of the proposed power supply.Index Terms-Fuel cell (FC) power conditioning system, remote area power supply (RAPS), three-phase boost-inverter.
