Inventory Testing Service
Do you have an inventory of spare Thyristors / Rectifiers but are not sure of their condition? We can provide a technician and a high voltage semiconductor testing unit. Our technician can test each spare power module you have and give you a report that provides you the status of each. The testing service can be provided for just travel expenses. Our goal is to get your technicians a complete list of reliable spares. If our technician discovers any power modules that are in need of repair he can provide a proposal to repair the faulty units. Give us a call to schedule an Inventory Testing Service visit. (360) 433-2886

Repairs - Drive Thyristors / Rectifiers
If you have Thyristor / Rectifier units that need repair we can help! Summit 's team has experience and expertise in testing, rebuilding and repairing many different types and brands of thyristor assemblies. Summit's experience includes but is not limited to the thyristor part numbers listed below. Also, you will see the individual components tested and if necessary replaced. We take all necessary precautions to ensure these modules are better than new when they go into one of your drives.

* All rebuilds are under warranty for one year.

* Summit can repair AC drive power modules (IGBT).

Description of Repairs

Part Description of Work Done
Testing All individual components are tested . If any part fails our rigorous testing we will replace all the parts listed below. This will avoid having a weak part causing a failure.
Cleaning Entire assembly is thoroughly cleaned. Heat sinks and backing plate are checked for pitting and other damage.
Gate Driver Board Existing gate drivers and leads are tested with an Oscilloscope and Signal Generator and if found to be faulty are replaced with factory replacement parts.
SCR Pucks Existing SCR pucks are tested and if necessary discarded. New pucks are installed and tested for proper operation. Torque is measured when reassembling units to ensure proper compression of SCR.
MOV Existing metal-oxide varistors are tested and replaced if necessary.
Capacitors All capacitors are tested to ensure standard charge and discharge rate. If shorted or faulty in any other way the capacitors are replaced with factory matched replacements.
Resistors The existing resistors are tested and replaced if necessary.
Component Connections All wire connections are tested and repaired if necessary. Poor connectivity can and will cause drive faults.
