3. Inverter arm design, control and protection

As we saw in the fascicule , the key link in the structure of an inverter is the basic cell, essentially made up of two three-segment switches, commonly referred to as the "bridge arm". The design of such a cell, an essential preliminary to the implementation of an inverter, requires the consideration of various sensitive aspects, the main ones being :

• the choice of power semiconductor components ;

• close control and protection of these same components;

• the interconnections between the elements of this cell.
