Applicant: SMA Solar Technology AG
Inventor： Sven Bremicker , Adrian Haering , Matthias Walter , Henrik Wolf , Joachim Laschinski
CPC classification number: H02H7/10 , H02H7/20 , H02H11/002 , H02J1/00 , H02J3/383 , H02J7/35 , H02M1/32 , H02M3/02 , H02M3/155 , Y02E10/563 , Y10T307/653
Abstract: In order to protect reverse currents, several strings of a photovoltaic generator, which are connected in small groups respectively via a DC/DC-converter, parallel to a common DC voltage intermediate circuit, the current which flows over each of the DC/DC-converter is detected and if a reverse current is detected flowing through one of the DC/DC converters, the converter is stopped by controlling the DC/DC-converter.
Abstract translation: 为了保护反向电流，与串联DC电压中间电路并联的多个分别以DC / DC转换器连接的多个光伏发电机串，流过每个DC / DC- 转换器，并且如果检测到流过DC / DC转换器之一的反向电流，则通过控制DC / DC转换器来停止转换器。
