1. Introduction
The control interface discussion between converter design engineers and the power semiconductor manufacturer can be reducedto the specification of power supply, control signal transfer andmechanical assemblyleading to a reduction of development costsand time. As a result the power semiconductor technologies madeavailable to a broader group of users. Basic design rules and handling / applicationrecommendations for IGCT gate units regardingpower supply, insulation and optical control interface, control-,diagnostics- and protection parameters as well as environmentalaspects are described in thisapplication note.Application note 5SYA 2031-06
2. Gate unit generations
This application note covers the gate units of several IGCT types.
The gate units can be grouped into two generations. Within a generation, the gate units are very similar in circuitry and functionality.
They only differ in mechanical size and the dimensioning of the gatedrive circuit. The application note is valid for IGCTs with both generation B and generation C gate units unless otherwise noted. Seriesand parallel connection with different generations is not recommended.
