This verified reference design provides an overview of how to implement a three-level three-phase SiC-based DC: AC grid-tie inverter stage. The higher switching frequency of 50KHz reduces the size of magnetics for the filter design and enables higher power density. This verified reference design provides an overview on how to implement a three-level three-phase SiC

We can measure temperature and humidity inside the fridge using a normal temperature-humidity indicator but relative humidity (RH) could be inaccurate in that case. The moment the fridge door is opened, RH will shoot up due to ingress or egress of moisture in the surroundings. The small sniffer device, described in this article, picks up
