Title:
SWITCHING REGULATOR
Document Type and Number:
Japanese Patent JPH0496649
Kind Code:
A
Abstract:

PURPOSE: To obtain a high output voltage by using a reactor connection- switching element having a characteristic of being able to be turned ON during the OFF period of a switch, through the element is OFF during the ON period of the switch.

CONSTITUTION: During the ON period of a switch 2, a current flows through a circuit composed of the switch 2, diode 17 and first reactor 3 so that energy is accumulated in the first reactor 3, while a current flows through a circuit composed of the switch 2, second reactor 16 and diode 18 so that energy is accumulated also in the second reactor 16. During the OFF period of the switch 2, the energy of the first and second reactors 3, 16 is released in a circuit com posed of the second reactor 16, diode 19, first reactor 3, capacitor 4 and diode 5. Because the first and second reactors 3, 16 are connected in series with each other at that time, the capacitor 4 is charged with electricity by the sum of the voltage of the first reactor 3 and that of the second reactor 16 so that a high output voltage can be obtained.
