| AD5430-18 (Automotive triple-phase PWM control board) |
|
| Features |
- Controls can be user-defined using by the Simulink model.
- Accepts resolver output signals directly.
- Maximum 20 kHz model cycle
(model-dependent – cannot be guaranteed by this specification)
- Triangle wave used for carrier signal.
- Dead band circuit included.
- Carrier frequency can be changed during operation.
- Two types of synchronous clock are provided, timer and angle. Switchable during operation.
- PWM output and A/D input can be synchronized with the synchronous clock.
- User settable delay time (angle) for sampling.
