A Duty Cycle Adjustment Strategy for Embedded Boost Power Factor Correction

Abstract:

The embedded boost power factor correction (PFC), which is realized by a storable duty cycle control method, has been verified that it can achieve good performance when the input voltage is standard sinusoidal signal. But the input current can not keep the good sinusoidal waveform all the time when the amplitude of the input voltage changes. In order to solve the problem, this paper presents a duty cycle adjustment strategy for embedded boost power factor correction. This strategy can adjust the duty cycle data synchronously when the amplitude of the input voltage changes. Its test results show that the adjustment strategy can achieve better performance to make the input current follow the shape and phase of the input voltage. The proposed duty cycle adjustment strategy can get the embedded boost power factor correction more effective and practical.
