Detailed Solution
Download Solution PDF- For class A the angle of the excursion is 360° and the current flows through the active device for the whole of the input cycle.
- For class B the angle of the excursion is 180° and the current flows through the active device for half of the input cycle.
- For class AB the angle of the excursion is >180° and < 360° and current flows through the active device for more than half of the input cycle.
- For class C the angle of the excursion is less than 180° and the current flows through the active device for less than half of the input cycle.
