PowerCage™
7000A-UM151E-EN-P - October 2018
A PowerCage is a converter module, consisting of the following elements:
•
epoxy resin housing
•
power semi-conductors with gate driver circuit boards
•
heatsinks
•
clamp
•
snubber resistors
•
snubber capacitors
•
sharing resistors
Each drive consists of three PowerCage rectifier modules and three
PowerCage inverter modules.
AFE type rectifiers use SGCTs as semi-conductors.
All inverter modules use SGCTs as semi-conductors.
The size of the PowerCage will vary depending on the system voltage.
The power semi-conductor usage in the converter section is as follows:
Configuration
Inverter SGCTs
2400V, AFE
3300/4160V, AFE
6600V, AFE
To prevent electrical shock, ensure the main

power has been disconnected before working on
the converter cabinet. Verify that all circuits are
voltage free using a hot stick or appropriate
voltage-measuring device. Failure to do so may
result in injury or death.
