Title:
モータ駆動システムおよびその制御方法
Document Type and Number:
Japanese Patent JP5216941
Kind Code:
B1
Abstract:
A motor drive system comprising: an inverter that supplies power to a three-phase motor; and a control unit that controls switching elements of upper and lower arms included in the inverter by switching between supply control of controlling the switching elements so that alternating current is supplied to three phases of the three-phase motor and suspension control of controlling the switching elements so that the supply of current is stopped. The suspension control involves: putting and keeping, in a conduction state, a switching element of at least one upper arm each corresponding to one of one or more phases through which current flows in a direction entering the three-phase motor at a timing at which the supply of current is stopped, and putting and keeping switching elements of rest of the upper arms and switching elements of lower arms in a non-conduction state.
