VN36 – Stm32 Break Functions and PWM Dead Time

VN36 (Video No:36). Video VN34 was about how to produce PWM signals with dead time by using complementary output CHx and CHxN? How to calculate pwm frequency, period, ARR and dead time values? Furthermore in this video we focused on how to use and adjust Break Funtions (BRK, BRK2, BRK_ACTH, OSSR, OSSI, AOE, Locking…) and PWM dead time management? How to use Comparators, Op-Amps? and an example of over current&voltage?

Notes;

• A definition of OSSR and OSSI;
• Set MOE bit to 1 to enable the OC and OCN outputs,
• Set the OSSR bit such that the outputs are forced to their idle mode when not running,
• Set OSSI bit such that the outputs are forced to their idle mode when MOE = 0.
