随着人们对全球能源需求的日益关注和环保意识的加强,电力电子设备应用面临着要提高效率的压力。智能电网、插电式混合动力汽车(PHEV)和纯电动汽车(BEV)、并网型光伏(PV)以及其他并网型可再生能源系统的出现推动着高效功率逆变器的发展。特别是针对新开发的光伏逆变器,其设计目标是最大程度上降低每瓦成本,最大程度上利用太阳能系统的电力,从而获得极佳的投资回报率。PV系统由于化石燃料的有限以及人们对
With people’s increasing concern about the global energy demand and the increasing awareness of environmental protection, the application of power electronic equipment is under pressure to improve efficiency. The emergence of smart grids, PHEVs and BEVs, grid-connected PVs and other grid-connected renewable energy systems have driven the development of high-efficiency power inverters. Especially for newly developed PV inverters, the design goal is to minimize the cost per watt and to maximize the use of solar system power for excellent ROI. PV systems are limited due to fossil fuels and people are right
