| titleOfInvention | Switching power circuit and circuit of power factor correction |
| abstract | Switching power circuit and circuit of power factor correction improve in the Partial peaks electric current at the high phase angle of exchange input waveform the distortion of the current waveform caused by becoming larger because of electric current continuous control and the deterioration of power factor.Phase angle detection circuit (60) be based on electric current continuous control initialization circuit (30) output, to the peak hold signal (S9) that is kept of the comparable voltage value of peak current value and peak holding of each switch periods with inductor current detection voltage when ono shot pulse (S5), detect preassigned phase angle, in the detection moment, output judges effective or invalid signal (S11) of the 2nd set pulse (S8) set by electric current continuous control initialization circuit (30).Selector circuit (70) is when input has invalid signal (S11) for indicating the 2nd set pulse (S8), only to detect that inductor current controls in a manner of becoming electric current Critical Control that switch element (4) are connected after zero in ZCD comparator (16), therefore, peak point current will not become larger. |
