ABB 3BHE024577R0101 PPC907BE  逆变器模块

光伏逆变器市场有着市场容量大，增长速度快的特点。针对于不同的应用场景，逆变器的功率等级也是千差万别。在光伏逆变器大家族中，组串式逆变器由于其体积小、安装灵活、使用场景多样化，近年来整体出货量呈现出高速增长的趋势，并且单台组串逆变器的最大功率范围，也逐年提升。

图1是一个典型的光伏发电系统，逆变器的主要功能是将电池板波动的直流电转变为与电网电压同相同频的交流电。组串式光伏逆变器的功率单元从电路结构上可分为升压单元(DC/DC)和逆变单元(DC/AC)。升压单元用于实现电池板的最大功率跟踪(MPPT), 根据电池板的连接方式以及逆变器的功率等级，升压单元可以一路或者多路不等。逆变单元用于将直流电压转换为工频的并网电压，最后通过隔离变压器接入电网。

ABB 3BHE024577R0101 PPC907BE inverter module

The photovoltaic inverter market has the characteristics of large market capacity and fast growth rate. For different application scenarios, the power level of the inverter is also very different. In the large family of photovoltaic inverters, series inverters due to their small size, flexible installation and diversified use scenarios, the overall shipment has shown a trend of rapid growth in recent years, and the maximum power range of a single series inverter has also increased year by year.

Figure 1 is a typical photovoltaic power generation system, the main function of the inverter is to convert the fluctuating direct current of the panel into alternating current with the same frequency as the grid voltage. The power unit of series photovoltaic inverter can be divided into booster unit (DC/DC) and inverter unit (DC/AC) from the circuit structure. The boost unit is used to achieve maximum power tracking (MPPT) of the panel, depending on the connection mode of the panel and the power level of the inverter, the boost unit can be one or multiple channels. The inverter unit is used to convert the DC voltage to the grid-connected voltage of the power frequency, and finally to the grid through the isolation transformer.
