Title: Power-factor improvement-type switching power-supply apparatus
Inventor: TANIGUCHI KATSUNORI
IPC: H02M7/06
Filed: 1993-09-10
Abstract: PURPOSE:To control the apparatus so as to improve its power factor without a loss by a method wherein, when an input current is outside the range of a prescribed hysteresis width, a first switching element is controlled so as to be turned on and off while a zero-volt switching operation is being conducted by a first switching element and a second switching element. CONSTITUTION:When a switching element Tr is set at on OFF state, the sum of voltages applied to a smoothing capacitor Cd and to a capacitor connected across rectification output terminals is applied to a capacitor Cr. When the switching element Tr is turned on, a current flows via a choke coil Ls for step-up and a choke coil Lc for resonance, and an applied voltage to the capacitor Cr becomes zero. Then, since an applied voltage to the switching element Tr becomes zero, the zero-volt and zero-ampere switching operation of the switching element Tr is conducted by turning on the switching element Tr. When a switching element Tc is turned off, the zero-volt switching operation of the switching element Tc is conducted.

Abstract: PURPOSE:To prevent generation of malfunction on other circuit by supplying an output from a common connecting point to the control terminal of a 2nd switching device, and feeding back the output of the 2nd switching device positively to the control terminal of a 1st switching device. CONSTITUTION:When a transistor(TR) 2 is energized with a trigger signal betaand the leading edge of a pulse w3 is outputted, a charge is discharged from a capacitor 5b and a level from a connecting point 7 is decreased. Then the capacitor 5b starts charging via a resistor 5a. However, when a trigger signal gammais inputted, the charge charged in the capacitor 5b is discharged via a diode 13. Then the capacitor 5b is again charged and the charge is again discharged by a trigger signal epsilon. Thus, when the trigger signal is inputted continuously, one short pulse trailing edge is obtained at all times in a prescribed laps of time from the newest trigger signal.
