Power factor correction (PFC) is an effective method to reduce harmonic current in power grid. A novel boost high power factor rectifier with UCC28019 is proposed. The UCC28019 8-pin active Power Factor Correction controller uses the boost topology operating in continuous conduction mode (CCM). It does not need multipliers. The use of the IC will make the PFC circuit design easily and the volume of the rectifier small. The fundamental principle of the proposed rectifier is introduced. Its sections such as current loop and over-current protection, voltage loop and over-voltage protection, and so on, are analyzed and designed respectively in detail. Experimental results of the designed 350W prototype prove that the boost high power factor rectifier is rational and reliable, its power factor can reach 0.992, and its application prospect is wide.

This paper designs a novel single phase high power factor rectifier with IR1150 as its main control chip, which main circuit uses boost topology. The fundamental principle of the proposed rectifier is introduced. The IR1150 control IC based on one cycle control is intended for boost converters for power factor correction operating at a fixed frequency in continuous conduction mode (CCM). The use of the IC will make the PFC circuit design easily, the volume of the rectifier small and the efficiency enhancing. The modules of the proposed rectifier such as current loop and over-current protection, voltage loop and over-voltage protection, soft start, and so on, are analyzed and designed respectively in detail. Experimental results of the designed 600W prototype prove that the boost high power factor rectifier designed is rational and reliable, its power factor can reach 0.994.

High Power Factor

A novel single-switch single-stage high power factor LED driver is proposed by integrating a flyback converter, a buck–boost converter and a current balance circuit. Only an active switch and a corresponding control circuit are used. The LED power can be adjusted by the control scheme of pulse–width modulation (PWM). The flyback converter performs the function of power factor correction (PFC), which is operated at discontinuous-current mode (DCM) to achieve unity power factor and low total current harmonic distortion (THDi). The buck–boost converter regulates the dc-link voltage to obtain smooth dc voltage for the LED. The current–balance circuit applies the principle of ampere-second balance of capacitors to obtain equal current in each LED string. The steady-state analyses for different operation modes is provided, and the mathematical equations for designing component parameters are conducted. Finally, a 90-W prototype circuit with three LED strings was built and tested. Experimental results show that the current in each LED string is indeed consistent. High power factor and low THDi can be achieved. LED power is regulated from 100% to 25% rated power. Satisfactory performance has proved the feasibility of this circuit.
