“…Furthermore, by recovering the energy stored in the inductance, the efficiency of the inverter can be improved slightly. Thus, by placing a snubbing network as detailed in [6] across the primary side of the transformer, not only is the voltagestress of the device significantly reduced, but the stored energy is recovered. The calculated spikes showed a high correlation to the low-power experimental results (Fig.…”

This paper covers the design and analysis of a compact inverter for photovoltaic (PV) and fuel-cell applications. The inverter is made up of two isolated ûuk converters working differentially to create a 60-Hz sinusoidal output. This enables direct dc/ac conversion with low device count and yields a simple drive-circuitry. This configuration will lower converter cost and size and can achieve an estimated efficiency of 95%. Key topics covered in this paper include analysis of the inverter topology and its design.I.

“…We are investigating an approach that uses two isolated ûuk converters in a differential mode to create a single-stage inverter [6]. The outlined configuration eliminates the need for a separate dc/dc-converter stage, and has only four main devices, all of which are low-side driven.…”

“…The isolated differential inverters are composed by two isolated high frequency dc/dc converters, which constitute differential output structure [27][28][29][30][31]. They can be divided into three categories according to their gain form: buck [27,28], boost [29], and buck-boost differential inverters [30,31].…”

With the background of power supply for the high precision apparatuses, an isolated high frequency DC-AC converter based on differential output structure is proposed. It is composed by two phase-shifted full bridges (PSFB) which share a common half bridge as the lagging leg on the primary side. Two current-doubler synchronous rectifiers (CDR) constitute differential output structure on the secondary side. The AC output is synthesized by the two PSFB-CDRs generating same DC bias and phase-reversed AC components. Compared to traditional solutions, the new circuit has the potential capability to obtain ultra-low distortion output voltage without using special control or compensations. Moreover, zero voltage switching (ZVS) is realized in the primary circuit within a wide load range, while zero current switching (ZCS) is achieved in the secondary circuit. Operation principles are analyzed and a 1kW prototype is built to validate the proposed scheme.Index Terms-Isolated high frequency DC-AC, differential output structure, ultra-low distortion, soft-switching.

“…Now, home power source is AC, on the other hand, the voltage provided by fuel cells is DC. Therefore, a DC-AC converter is essential for the home-use cogeneration system [2][3]. In fuel cells applications, small input current-ripple is essential because the fuel cell chemical reaction time is much slower than commercial frequency.…”

In fuel cells applications, current-ripple reduction is essential for conversion efficiency and life span. This paper analyzes the pulse-link DC-AC converter for fuel cells applications operated in zero-current-slope mode. As the result, in zero-current-slope operation mode, input-current-ripple is reduced. Furthermore, in this operation mode, the parameters of series LC circuit which is worked as ripple canceling are less values.
