Abstract | In this paper we propose to study the use of Zero-Current-Switched Quasi-Resonant Converters as Power Factor Preregulators with two possible types of control: multiplier approach control and voltage -follower approach control. The former allows us to obtain almost ideal operation, but requires switching-frequency modulation each line half-cycle, input current feedback loop and specific controller. The latter allows us high power factor (0.98 - 0.96) and low total harmonic distortion (15 - 26%) with a very simple control method which can be implemented with a standard controller. |
