Rectifying circuit for a multiphase electric machine |
摘要 |
Cathode-anode voltage across free-wheeling diodes in an active rectifier is used in the determination of switching points when the free-wheeling diode is forward biased. Hysteretic switching is accomplished through the selection of conductive and non-conductive switching threshold. The switching thresholds are further selected to prevent voltage oscillations at zero current crossings and reduce delays during deactivation to prevent cross-conduction. |
