  • Patent number: 9030856
    Abstract: In a high voltage inverter device switching an input voltage to apply an exciting current to an excitation winding of a transformer and output an alternating-current high voltage from an output winding to supply the high voltage to a load from output lines, a point on the output line is connected to a frame ground. Each of a first and a second winding of the electrical leakage detecting transformer is interposed in series with the output line on a side where current flows out of the point and a side where current flows into the point respectively. A detection voltage Vd outputted from an amplifying winding is compared by a comparison voltage Vref, and an electrical leakage detection signal Sd is outputted when Vd>Vref. The first and second winding are opposite in winding direction to each other and equal in number of turns.

  • Publication number: 20150123402
    Abstract: Magnetic components that can be used to provide normal mode and common mode inductance in a power system, such as a wind-driven doubly fed induction generator system, are provided. The magnetic components can include a structure that combines both normal mode inductors and common mode inductors on a common core. In particular, the magnetic components can include specific winding and core arrangements which couple a common mode inductor and a normal mode inductor onto a single core with at least three legs. The structure of the magnetic components can be smaller in size, can have lower weight, and can have a lower cost than typical solutions to providing common mode and normal mode inductance in a power system.
