Characteristics of Forced-Commutated Switches
On State
- Positive control signal
- Transistor: continuous base current
- MOSFET, IGBT: Continuous gate voltage
- GTO: gate current trigger
- Maintain unidirectional conduction
Off-State
- Negative control
- Transistor: continues reverse base voltage
- MOSFET, IGBT: continuous gate voltage
- GTO: reverse gate current trigger.
- Block forward voltage
