Caption
The consequences can be costly, ranging from production downtime to compromised equipment and even safety hazards. Certainly, capacitors are indeed responsible for 30% of power electronics failures, as illustrated in Fig. 1(a).
This paper proposes a single-phase dc-ac converter designed for conditions where capacitors are not recommended for specific applications. The topology consists of two parts: a low-frequency H-bridge converter and a solid-state power filter (SSPF) capable of generating a sinusoidal voltage output for the load. The schematic representation in Fig. 1(b) illustrates the elimination of passive components, setting this design apart from existing literature.
