CONTROLLER

Coil controllers come in many different shapes and sizes depending on the users needs. Depending on the needed functions they control Power, Modes, Audio, safety functions and much more. Most of the time these controllers are self built or at least partly self built. There are many great minds out there with new ideas to implement functions into controllers. These new ideas get copied and improved all the time and the designs tend to get more and more complicated and comprehensive.

In a DRSSTC, at least two “intelligent” parts are needed to enable function. First, a controller which is handled by the user to generate the wanted frequencies. Second, a gate driver mounted on the DRSSTC to switch the IGBTs with the applied frequencies.

Gate Driver

The gate driver is placed on the DRSSTC in an enclosed metal case which is connected to the Coil GND. The driver output is connected with a 1:1 current transformer to to the IGBT bridge. For more information see here.

Control functions	– Frequency input with optical fiber – Overcurrent detection (OCD) – Frequency feedback for frequency alignment – LED indicator for Power, OCD and input frequency

Mixer Coil Controller

Because of more then 2 DRSSTC available, a new controller was needed. For more information see here.
