Steuereinrichtung für Leistungskonverter und Steuereinrichtung für Fahrzeug mit elektrischem Motor

摘要

Disclosed is an apparatus for realizing a small apparatus by making element currents uniform in the dipolar modulation mode. The zero voltage period in the dipolar modulation period is made shorter than other voltage output periods. Accordingly, currents of switching elements constituting the main circuit of an inverter can be made uniform.
