ACTIVE CLAMP FOR MOTOR DRIVER |
摘要 |
<p>An apparatus includes a clamp control circuit configured to control a first current to have a magnitude substantially equal to that of a second current when the second current has a first flow direction. The clamp control circuit is configured to control the first current to be substantially zero when the second current has a second flow direction. A method includes determining a value of a first current, controlling a second current to have a substantially zero value when the first current flows in a first direction, and controlling the second current to have a magnitude substantially equal to that of the first current when the first current flows in a second direction. The first current flows in the first direction when a winding of a motor is being supplied with energy and flows in the second direction when the winding of the motor is discharging energy.</p> |
