Circuit Board 91026: Power Transistors and GTO Thyristors

New 

In the Power Transistors and GTO Thyristors course, students perform practical exercises that demonstrate the use of several power electronic, self-commutated switches. The course contains six types of switches that are implemented with a ­MOSFET, an isolated-gate bipolar transistor (IGBT), a fast IGBT, a bipolar resistor, a Darlington resistor, and a GTO thyristor. Learning of switches is expanded with a Driver section, consisting of an opto-isolator and driver for power thyristors; a Load section, consisting of resistive and inductive components; and general-purpose, fast, and ultra-fast free-wheeling diodes.
