A limiting resistor (RL) is connected in series with the negative power supply line (11) of the DC power supply bus and is designed to limit the charging current of the bus capacitor (Cbus). An inverter module has upper transistors (T2, T4, T6) and lower transistors (T1, T3, T5) in series of the normally ON field-effect type, and several Grid control devices (CT1-CT6) allow each to apply a Grid voltage to the transistors for controlling each transistor so as to turn off or to turn on. A start-up source (Sd) is connected in parallel with the limiting resistor and to each Grid control device (CT1, CT3, CT5) for the lower transistors, and is configured for charging with a negative voltage when the power converter starts up."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power converter comprising an inverter module using normally ON field-effect transistors","description":"A power converter includes a DC power supply bus having a positive power supply line (10) and negative power supply line (11).
