PRODUCT DETAILS:

From manufacturer

The Lab-Volt IGBT Chopper/Inverter consists of seven insulated-gate bipolar transistors (IGBT) mounted in a half-size
EMS module. Six IGBTs are used to implement choppers and inverters. These IGBTs are protected against a
variety of severe operating conditions, such as short-circuits, overvoltage, overcurrent, and also overheat. The
seventh IGBT and a dumping resistor allow smooth dissipation of excess energy at the dc bus. The dumping
circuit can be activated through the use of a toggle switch on the front panel.

The module switching control section allows 0/5 V pulse signals from either the Data Acquisition and Control
Interface, Model 9063, the Chopper/Inverter Control Unit, Model 9029, or any compatible 0/5 V control unit, to
be applied to the gating circuits of the IGBTs. The signals are input in the IGBT Chopper/Inverter module
through a 9 pin connector. Six miniature banana jacks are used as test points to monitor the pulse signals using
an oscilloscope. These jacks can also be used to inject 0/5 V pulse signals from an alternate control unit, as well
as to inhibit each gating circuit. The IGBT Chopper/Inverter module also includes a synchronization output to
trigger an oscilloscope when observing the switching control signals as well as a switching control disable input
that allows all six IGBTs in the chopper/inverter section to be switched off.

The IGBT Chopper/Inverter, Model 8837-A, is an earlier version of the IGBT Chopper/Inverter, Model 8837-B.
