1-Phase DC-AC 3-LEVEL CASCADED MATRIX INVERTER - copy

00:33:04

Notice that each stage is connected to the next “in series” to produce an output which adds up. The output as indicated is series-resonant to obtain a Vo roughly equal to 3xVbatt.

TOPOLOGY: each full bridge has 3 valid switching states (1, 0, -1) and one redundant state. Therefore 3 full bridges have 9 switching states and 3 redundant states in total.
