High Voltage Power Supply Module Size Is Shrinking
High Voltage Power Supply Module Size Is Shrinking Following a lead from their low voltage cousins, high voltage power supplies have moved to modular localized solutions, although high voltage must be treated very differently. High voltage power supply designers face the same problems as low voltage designers, plus the additional co...

Components and Methods for Current Measurement
Current sensing is used to perform two essential circuit functions. First, it is used to measure “how much” current is flowing in a circuit, which may be used to make decisions about turning off peripheral loads to conserve power or to return operation to normal limits. A second function is to determine when it is a “too much” or a fau...
