What is a dual converter?
As the name suggests Dual Converter has two converters, one converter works a rectifier (Converts AC to DC) and other converter works as an inverter (converts DC into AC). Both converters are connected back to back with a common load as shown in above picture. To learn more about Rectifier and Inverter, follow the links.
What is an ideal dual converter?

Types of Dual Converters: They include single-phase dual converters and three-phase dual converters, differing in the type of AC supply they convert.
What is a dual converter & a semi-converter?
Dual Converters offer four-quadrant operation as here both voltage and current attain positive or negative polarity. We have already discussed that semi-converters are single quadrant converters implying that, the complete range of firing angle of load voltage and current exhibit single polarity.
What are the different types of dual converters?
Types of Dual Converters: They include single-phase dual converters and three-phase dual converters, differing in the type of AC supply they convert. Applications: Dual converters are used in DC motor control, reversible DC needs, and industrial variable speed DC drives.
Can a dual converter be operated without circulating current?
The dual converters can be operated with or without circulating current, only one converter operates at a time. When circulating current is not present however, Other converter is completely blocked by inhibiting gate pulses. The back to back connection of two fully controlled converters across the load circuit is named as Dual converter.
