A method for compensating for dead time non-linearities in a pulse with modulation controlled switching scheme

摘要

A method for compensating for dead time non-linearities in a pulse width modulation (PWM) controlled device (103) including obtaining a motor data signal (14), (2), generating a duty cycle of the motor voltage (22) responsive to the motor data signal (14), (6), determining a compensation value responsive to the duty cycle of the motor voltage (22), (8), generating a compensated duty cycle (18), (20) in response to the compensation value and the duty cycle of the motor voltage (22) and introducing the compensated duty cycle (18), (20) to the PWM controlled device (103), (12). In addition, a medium encoded with a machine-readable computer program code for compensating for dead time non-linearities in a pulse width modulation (PWM) controlled device (103), the medium including instructions for causing controller (100) to implement the aforementioned method.
