Title:
SWITCHING REGULATOR CIRCUIT
Document Type and Number:
Japanese Patent JPS5833728
Kind Code:
A
Abstract:
PURPOSE:To decrease a ripple voltage component of a DC output voltage and radiation noise, by additionally providing an inverter, a switching transistor (TR) and a reactor for a known circuit. CONSTITUTION:A TR8 and a reactor 9 are added to a load current supply path and a diode 3 is inserted between a connecting point of the TR8 and the reactor 9 and ground. With a TR1 turned on, the current in a reactor 2 starts increasing. During this increase, the TR8 is turned off and an output voltage +V0 is decreasing, but the speed of decrease of the +V0 is slow due to the current flowing to the reactor 9. Thus, with the TR8 turned on, a positive voltage induced in the reactor 2 is given to a load via the TR8 and the reactor 9 as a DC output current. In this case, the current flowing to the reactors 2 and 9 starts decreasing. During this decrease, the output voltage +V0 is increasing.
