Abstract

PURPOSE: To prevent a short by firing the thyristor to be ignited next after making sure the current is naturally turned off independently of the load power-factor and to control the output voltage by controlling the zero interval of current.
CONSTITUTION: The transformer T1 has a 30° phase shift between the secondary outputs of three-phase 50 Hz U1, V1, W1 and the ones U2, V2, W2. Three-phase bridges Bf and Bb of thyristor-structure are connected with each other in parallel reversely and are supplied three-phase 50Hz power, the three-phase bridges Af and Ab are in the same way. The three-phase bridges Af, Ab and the ones Bf, Bb are connected in series to make a mesh connection, one terminal of the Af-Ab and that of the Bf-Bb ar connected to the output terminal of a single phase 60 Hz so that the output of a single phase 60 Hz may be avaiable through the transformer T2.
