Set of 13 overlay masks line-commutated converter
Detection of the applied mask is automatic, thus establishing a preset base state in the converter controller unit (735 122) to prevent the destruction of components through incorrect control commands, thereby simplifying operation of the controller unit. The supplied overlay masks reduce considerable the effort for the experiment set up. Overlay masks do not physically cover necessary connections, they do graphically show the given circuit as a schematic:
- M1/M3, uncontrolled
- M1, controlled
- M3, controlled
- B2, uncontrolled
- B2, controlled
- B2, (un-)controlled for 3 half-waves
- B6, uncontrolled
- B6, controlled
- B6, (un-)controlled for 2 half-waves
- B2, doubled for polarity reversal (B2C)A (B2C)
- W1, anti-parallel 1p
- W3, anti-parallel 3p
- Triac
