Today, 18:32Not sure how you calculate "load switching" frequency. In case of unipolar modulation scheme, output pulse frequency is double the PWM frequency. But...5 replies | 160 view(s) -
Today, 18:05I see several issues with your simulation. 1. The models are corrupted, You have apparently edited the subcircuit port names. I reverted to the...5 replies | 89 view(s)
