| Abstract: | The two aims of single-phase active power factor corrector(PFC) are unitary input power factor and low output voltage ripple.In terms of control and protection,input AC voltage,inductor current and output DC voltage should be detected at the same time.But some algorithms need not to detect all of them.In the paper,one of the single-phase active PFC’s without input voltage are analyzed in theory,then simulated by means of MATLAB/SIMULINK,and finally implemented digitally based on TMS320F28335,a DSP supporting floating calculations.The gained results prove the theoretical analysis. |
