The SCR / thyristor trigger module SKHIT 01 has been designed for triggering half controlled bridges.
When switching on a DC-link voltage converter the DC-link capacitors are uncharged and are, thus, signalizing a short circuit situation to the applied supply voltage. Therefore, the charge current has to be limited to the rated value by switching suitable circuits; SEMIKRON prefers to realize those circuits without electromagnetic components such as relays or contactors. Instead of an uncontrolled B6-diode input bridge (B6U), a half-controlled diode thyristor bridge is used (B6H). At the beginning of the switch-on process the thyristors are blocked, the DC-link capacitors are charged via diodes D1 - D3 and Rcharge (fig. 3). After having finished the charging process, the thyristors have permanently to be triggered by a driver stage such as the SKHIT 01.
