Title:
DISCHARGE CONTROL DEVICE FOR POWER CONVERSION SYSTEM
Document Type and Number:
Japanese Patent JP2011188711
Kind Code:
A
Abstract:

To solve a problem wherein there is a possibility that a current flows in a motor generator 10, when discharging a capacitor 16 by shorting both electrodes of the capacitor 16 by turning a switching element Swp on a high potential side and a switching element Swn on a low potential side into an on-state.

Discharge control is performed by output of a discharge command dis in an abnormality to drive units DU for an upper arm and a lower arm of the U-phase. In this case, by manipulating an insulation element driving unit 60, an ON manipulation command is prevented from being input into drive units DU of V-phase and W-phase upper arms and lower arms.
