It seems deceptively simple to establish galvanic isolation with the help of optocouplers between circuits that operate at different ground potentials. Optocouplers draw power from the isolated ...

Dusseldorf, Germany: The PS9402 insulated gate bipolar transistor (IGBT) drive optocoupler from Renesas Electronics integrates IGBT protection. It comprises a gallium-aluminium-arsenide (GaAlAs) LED ...

Here is a simple circuit you can use to measure the attack and release times of photoresistor-type optocouplers that often find use in audio compressors or volume-control circuits (figure). The design ...

Renesas Electronics has announced the availability of a drive optocoupler with 'industry leading' fast switching and integrated insulated gate bipolar transistor (igbt) protection function. The PS9402 ...

For inverter applications, such as motor drives, uninterruptible power supplies, switchmode power supplies, high intensity lamp ballasts, and induction heating, the gates of insulated gate bipolar ...
