IGBT Chopper/Inverter



The IGBT Chopper/Inverter is one of the Power Electronics Devices that can be added to the 2 kW Electromechanical Training System to allow training in power electronics. The Power Electronics Devices are used to filter and convert electrical power flowing in electric circuits. They come as half-size EMS modules equipped with a steel front panel. Internal electrical components are identified on the module front panel by silkscreened symbols.

This module consists of 7 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 overheat. The seventh IGBT and an external 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.
