Abstract: A reversible converter includes a first field effect transistor and a second field effect transistor that are coupled in series between a first terminal and a second terminal for a DC voltage. A first triac and a second triac are also coupled in series between the first and second terminals of the DC voltage. Midpoints of the series coupled devices are coupled, through an inductive element, to first and second terminals for an AC voltage. Actuation of the transistors and triacs is controlled in distinct manners to operate the converter in an AC-DC conversion mode and a DC-AC conversion mode.

Abstract: A reversible converter includes a first field effect transistor and a second field effect transistor coupled in series between a first terminal and a second terminal for a DC voltage. A first thyristor and a second thyristor are coupled in series between the first and second terminals for the DC voltage. A third thyristor and a fourth thyristor are also coupled in series between the first and second terminals for the DC voltage terminals, but have an opposite connection polarity with respect to the first and second thyristors. A midpoint of connection between the first and second field effect transistors and a common midpoint of connection between the first and second thyristors and the third and fourth thyristors are coupled to AC voltage terminals. Actuation of the transistors and thyristors is controlled in distinct manners to operate the converter in an AC-DC conversion mode and a DC-AC conversion mode.

Abstract: A circuit for balancing a voltage across a semiconductor element series-connected with other semiconductor elements of the same type may include a comparator configured to compare data representative of a voltage across the semiconductor element with a reference voltage, and a resistive element of adjustable value and configured to be controlled by the comparator.
