Aggiungi al carrelloTaschenbuch. Condizione: Neu. Neuware -A high efficiency, low profile and high step-up dc-dc converter is proposed for low dc voltage renewable energy system. Generally, the power source such as photovoltaic array and the fuel cell stack have low voltage output because of that a high voltage step-up converter is required to boost the voltage much higher than the voltage level for front-end application. The efficiency and voltage gain of conventional dc-dc converter are limit due to the parasitic components. In order to solve the above mentioned problem, the proposed converter is based on active clamp technique and the converter is the combination of a forward converter and a flyback converter. Multiple secondary windings can be employed for low profile design and help to reduce high transformer copper loss and high output rectifiers conduction losses. The proposed converter is confirmed with experiments on 250-W prototype and the maximum efficiency of 94% was measured at full load.Books on Demand GmbH, Überseering 33, 22297 Hamburg 72 pp. Englisch.

Aggiungi al carrelloTaschenbuch. Condizione: Neu. Neuware -Solar photovoltaic (PV) has emerged as one of the most favourable renewable energy source in power generation. This is due to the abundance of solar irradiance, easy implementation and environmental friendly which it does not produce pollutants during the operation. In term of economical aspect, it is always the challenge to ensure the installed photovoltaic system to perform at its maximum available capacity in order to maximize the return of investment. One of the most economical and efficient way is by employing maximum power point tracking (MPPT) to the PV system to adjust the optimal operating point for the PV system to generate maximum power. The maximum power point is where the matching of operating point between PV array and power converter to maximize the power transfer from the PV array to the power converter. This often causes the conventional MPPT algorithm to trap at the local peaks, which results in power loss. Recent years, with the availability of vast and low cost micro controllers, the soft computing (SC) based MPPT methods are attracting considerable interest among researchers.Books on Demand GmbH, Überseering 33, 22297 Hamburg 76 pp. Englisch.

Neuware -Ein hocheffizienter Gleichspannungswandler mit niedriger Bauhöhe und hohem Aufwärtssprung wird für ein Niederspannungs-Gleichstrom-Energiesystem für erneuerbare Energien vorgeschlagen. Im Allgemeinen haben die Stromquelle, wie z.B. die Photovoltaikanlage und der Brennstoffzellenstapel, eine niedrige Ausgangsspannung, weshalb ein Hochspannungs-Aufwärtswandler erforderlich ist, um die Spannung viel höher als das Spannungsniveau für die Front-End-Anwendung anzuheben. Der Wirkungsgrad und die Spannungsverstärkung eines konventionellen Gleichspannungswandlers sind aufgrund der parasitären Komponenten begrenzt. Um das oben erwähnte Problem zu lösen, basiert der vorgeschlagene Wandler auf der aktiven Klemmtechnik, und der Wandler ist die Kombination aus einem Durchflusswandler und einem Sperrwandler. Mehrere Sekundärwicklungen können für ein Design mit niedrigem Profil verwendet werden und helfen, die hohen Kupferverluste des Transformators und die Leitungsverluste von Gleichrichtern mit hoher Ausgangsleistung zu reduzieren. Der vorgeschlagene Wandler wurde mit Experimenten an einem 250-W-Prototyp bestätigt, und der maximale Wirkungsgrad von 94% wurde bei Volllast gemessen.Books on Demand GmbH, Überseering 33, 22297 Hamburg 76 pp. Deutsch.
