Abstract：As a kind of winch driven by motor，electric winch has more excellent performance of cable control.However，in the process of retracting and releasing the cable，the drum inertia of the electric winch will change with the change of the cable stock. This unknown inertia change will lead to mismatching of motor ...

Abstract：Space vector pulse width modulation（SVPWM）strategy is one of the key technologies for threelevelinverters. However，conventional three-level SVPWM often experiences neutral point potential（NPP）oscillation and high switching loss when addressing the neutral point potential balancing issue. To tackle thischall...
