    摘要: An insulated gate bipolar transistor having a gate electrode (7) and an emitter electrode (9) is provided in a transistor region. A termination region is arranged around the transistor region. A first N type buffer layer (18) is provided below an N type drift layer (1) in the transistor region. A P type collector layer (19) is provided below the first N type buffer layer (18). A second N type buffer layer (20) is provided below the N type drift layer (1) in the termination region. A collector electrode (21) is directly connected to the P type collector layer (19) and the second N type buffer layer (20). An impurity concentration of the second N type buffer layer (20) decreases as a distance from the collector electrode (21) decreases. The second N type buffer layer (20) does not form any ohmic contact with the collector electrode (21).

    摘要: The present invention discloses an underwater building unit and its installation and application methods. It includes a caisson with both ends open and is composed of two rows of box boards being not intersected with each other. Each row of box boards consists of a set of stake-plate body combinations and the bind members between every two adjacent stake-plate body combinations. A positioning beam is located on the top of the box boards and connects the two box boards. There is a cross rib at the middle part of the outer surface of each bind member. The open caisson is made up of small components of low weight. So it is easy for installation and could be extended unlimitedly as required. In addition, the underwater building unit has low underwater condition requirement and is relatively stable, thus the underwater building is quite firm and has a long life. Each component of the open caisson can be industrially manufactured on land so as to lower the cost and free of the influence of stormy waves.

    摘要: In one example, a ground fault circuit interrupter is provided. It may include a current imbalance detection circuit configured to provide a leakage signal and a main processing circuit including a processor. The leakage signal may correspond to a current imbalance between a supply path and a return path. The processor may be configured to receive the leakage signal, analyze a time pattern of the leakage signal, determine whether a ground fault exists based on analysis of the time pattern, and generate a first trigger signal if the ground fault is determined to exist. The ground fault circuit interrupter may further include a back-EMF detection circuit configured to provide a back-EMF detection signal. Methods for detecting and responding to a ground fault are also provided.
