器件型号：BOOSTXL-DRV8323RH 您好！
例如，如果启用了"制动"并且 brakingMode == HARDSWITCH_BRAKE_MODE，则执行以下代码，关闭/禁用两个 NFET，我不确定 这是否类似于 BRAKE？
static inline void HAL_exitBrakeResetPWM(HAL_MTR_Handle handle)
{
HAL_MTR_Obj *obj = (HAL_MTR_Obj *)handle;
uint16_t cnt;
for(cnt=0; cnt<3; cnt++)
{
// setup the Dead-Band Generator Control Register (DBCTL)
EPWM_setDeadBandDelayMode(obj->pwmHandle[cnt], EPWM_DB_RED, true);
EPWM_setDeadBandDelayMode(obj->pwmHandle[cnt], EPWM_DB_FED, true);
// setup the Action-qualifier Continuous Software Force Register (AQCSFRC)
EPWM_setActionQualifierContSWForceAction(obj->pwmHandle[cnt],
EPWM_AQ_OUTPUT_A,
EPWM_AQ_SW_DISABLED);
// setup the Action-qualifier Continuous Software Force Register (AQCSFRC)
EPWM_setActionQualifierContSWForceAction(obj->pwmHandle[cnt],
EPWM_AQ_OUTPUT_B,
EPWM_AQ_SW_DISABLED);
}
obj->flagEnablePWM = false;
return;
}
相比杨明2年前发布的,它 只打开低侧 NFET,电动机内部的能量收集器,有什么不同的2种方法 ?
static inline void HAL_enableBreakPwm(HAL_Handle handle)
{
HAL_Obj *obj = (HAL_Obj *)handle;
// Force high side off, low side on
PWM_setActionQualContSWForce_PwmA(obj->pwmHandle[PWM_Number_1], PWM_ActionQualContSWForce_Clear);
PWM_setActionQualContSWForce_PwmB(obj->pwmHandle[PWM_Number_1], PWM_ActionQualContSWForce_Set);
PWM_setActionQualContSWForce_PwmA(obj->pwmHandle[PWM_Number_2], PWM_ActionQualContSWForce_Clear);
PWM_setActionQualContSWForce_PwmB(obj->pwmHandle[PWM_Number_2], PWM_ActionQualContSWForce_Set);
PWM_setActionQualContSWForce_PwmA(obj->pwmHandle[PWM_Number_3], PWM_ActionQualContSWForce_Clear);
PWM_setActionQualContSWForce_PwmB(obj->pwmHandle[PWM_Number_3], PWM_ActionQualContSWForce_Set);
return;
} // end of HAL_enableBreakPwm() function
