HERIC inverter (1-phase application)
HERIC (Highly Efficient and Reliable Inverter Concept) is a well-known topology for photovoltaic systems. This is a configuration in which two anti-parallel auxiliary switches are added to the conventional H-bridge inverter. These switches can pass freewheel current through the shortest route during the period when the output voltage of the H-bridge inverter is zero, and can improve loss and noise.
- Six switches conform this topology, in which the four on the H bridge switch at high frequency, and the two external ones switch at grid frequency.
- Lower cost SJ-MOSFET
- Lower loss SiC MOSFET, IGBT
- Smaller Package choises from 3-leads, 4-leads or 7-leads,
