Abstract
Voltage inverter provided with four switching cells (Qto Q) to be connected to the terminals of a DC voltage source (Vdc), each comprising two semiconductor switches (I, I, I, I, I, I, I, I) installed in series, these switches having a common point (A) to be connected to an AC current source (Mac) with three phases (p, p, p) and a neutral (n), the connection being made onto one phase (p, p, p) for three of the cells (Q, Q, Q) and onto the neutral (n) for the fourth cell (Q). Each cell (Qto Q) cooperates with a semiconductor electrical isolating device (S, (Sand S)) to be put into a turn-off state if the cell should fail, this isolating device (S, (Sand S)) being arranged either on the connection to the AC current source (Mac), or on connections to the terminals of the DC voltage source (Vdc).
