is in the ignition state, this drinking time VTd
During this period, it cannot be commutated to the next Up or WN,
The current will concentrate on the determined arm, and the DC current will flow through the thyristor transformer 14, receiving the DC biased magnetism and heating it. As a result, the lifespan of the thyristor transformer 14'? f: When there are a large number of anchors and thyristors in parallel, problems such as destruction of the thyristors often occur.
