... Lstray is the total value of the critical loop inductance consisting of L1 and L2. L2 is the part of Lstray that is located in the synchronous rectification path, i.e. between GND and phase node. L1 is the part of the L stray that is not part of L2. Another assumption is that the HS-MOSFET is switch ...

History of electric power transmission



The history of the technology of moving electricity far from where it was generated dates from the late 19th century. This includes movement of electricity in bulk (formally referred to as ""transmission""), and the delivery of electricity (""distribution"") to individual customers. The distinction between the two terms did not exist in early years and were used interchangeably.
