Brushless-motor driver in PWM mode |
摘要 |
In a driver of a brushless motor performing synchronous rectification PWM operation, switching is performed at an arbitrary timing between a synchronous rectification PWM operation and one-way PWM operation to prevent a negative current for the power supply, and thus preventing increase of a power supply voltagedue to the negative current, thereby implementing high performance and high reliability.
