4 Key Challenges to Implement OPP and How TI Has Solved Them

Implementing a robust OPP solution introduces three complex challenges:

1. Synchronous PWM pulse generation
2. SVPWM to OPP transition
3. Dynamic response and robust closed loop control

These challenges demand differentiated MCUs that support industry-leading real-time control performance and unique features. TI's OPP design solved these challenges with F29x real-time microcontrollers. Key F29x MCU features that enable this are:

• High-performance C29 CPU core optimized for real-time motor control
• Type 5 ePWM enabling accurate edge placement, multiple edges within a PWM period, and active and shadow register capabilities
• Tightly coupled CPU-PWM minimizing CPU overhead
