Abstract :
This paper describes a positive-feedback situation which arises due to interaction between the constant-power input characteristic and the input-filter impedance characteristic, in a d.c. chopper controller. The limiting condition for convergent oscillation is predicted and confirmed by practical measurements on a 250 A, 400 V chopper.
