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,
