1. This makes the rotary converter a hybrid dynamo and mechanical rectifier. 2. Two Westinghouse 250 kW rotary converters produced 500 V DC for the trams. 3. Also, five rotary converters were installed to supply the required DC power. 4. Rotary converters provided high current DC power for industrial electrochemical processes such as electroplating.5. It contained three 250 kW Westinghouse rotary converters . 6. General Electric installed rotary converters in B & O's powerhouse near Mt. 7. Former machinery transmitters like the Alexanderson alternator were, strictly speaking, rotary converter plants. 8. Other furnace types used, include top-blown rotary converters and short rotary furnaces. 9. Rotary converter plants were also used for coupling power grids of different frequencies and operation modes.10. The rotary converter can directly convert, internally, any type of electric power into any other.
