Improved Control for Isolated Cycloconverter-type Dual Active Bridge DC/AC Converter

As isolated converters are incorporated in a larger number of applications such as photovoltaic generation or electric vehicle chargers, consumers are looking for cost efficient and compact solutions leading to a desire for large power density and high efficiency designs. Typical two-stage cascaded dual active bridge inverter designs contain a large capacitor bank for the DC bus limiting their power density, and the inclusion of two converters …
