The gate current indicates a peak current of about 200mA and a time constant of about 32µS — essentially 47Ω * 0.68µf. The leading edge spike is caused by the inductance of the 1Ω shunt resistor used.

Not knowing this, I previously adapted a cheap ‘DC51’ thyristor controller (circuit diagram far below) to run a small milling machine ... Therefore, the the SCR gate driver (Q2 and R15) connects the ...

Transistor Q2 acts as a clamp to disable the SCR gate drive voltage when the AC line is above about 15V. When the line voltage is below that value, the optocoupler controls the gate of the SCR. A ...

Understand the essential aspects of gate drivers. This post covers unique issues related to gate driver dc-dc converters.

Vishay Intertechnology's VO1263AB solid state relay, dual photovoltaic MOSFET driver offers a combination of high open-circuit voltage and short-circuit current.

IXYS Integrated Circuits Division (ICD), Inc., a wholly owned subsidiary of IXYS Corporation (NASDAQ:IXYS), today announced that the IXD_614SI family ...

The highly integrated 3.3 kV XIFM plug-and-play digital gate driver is designed to work out-of-the-box with high-voltage SiC-based power modules to simplify and speed system integrationCHANDLER ...

Permanent magnet dc motors need a chunky inductor in series with them if they are fed from an SCR (thyristor) based mains power controller. It is (probably!) possible to safely interface an Arduino to ...
