"automatic reset N.C. series connected thermal overload protection, two moisture sensing probes, prelubricated shaft bearings and class F insulation."
It is proposed a novel hybrid asymmetric 9-level inverter in which an asymmetric 5-level inverter and an H-bridge inverter with equal dc bus voltage are series connected.
"automatic reset N.C. series connected thermal overload protection, two moisture sensing probes, prelubricated shaft bearings and class F insulation. *Efficiencies include all mechanical losses including mechanical seals."
