Enhancing motor-drive apps with added safety, the ACPL-785J isolation amplifiers include both short-circuit and overload detection and allow direct measurement of motor phase currents in power ...

The isolation amplifier circuit of Figure 1 is simple but accurate. With the values shown it converts 0 to 5V DC or low frequency signals with unity gain, but you can adjust the gain by changing R4.

Electric motors that are either poorly maintained or which lack the proper electrical protection are the second greatest cause of electrical fires. So says the Factory Mutual Research Corp., a ...

Designers often categorize power converters into two basic types: isolated and nonisolated. These categories refer to the relationship between the input power ground and the output power ground. Many ...

Isolation is a means of preventing current from flowing between two communicating points. Typically, isolation is used in two situations. The first is where there's the potential for current surges ...

Gree Electric Appliances Inc of Zhuhai has been granted a patent for an isolation circuit system and signal isolation method. The system includes a power management unit, digital logic circuit, and ...

Picking up where we left off in Part 1, we need to explore some methods to mitigate problems caused by unpredictable ground currents.
