Title:
CHOPPER TYPE DC/DC CONVERTER
Document Type and Number:
Japanese Patent JPS61262079
Kind Code:
A
Abstract:
PURPOSE:To efficiently stabilize an output by providing a circuit for making the prescribed current flow in response to the output, the load winding of a saturable reactor of a magnetic amplifier and a rectifying diode between a switch element and an output smoothing circuit. CONSTITUTION:When a switch element 2 is turned ON, a saturable reactor 18 stops an input voltage for the prescribed period and then saturates, and supplies a voltage of a pulse width with an output voltage as a specified value to the cathode side of a diode 22. When the element 2 is turned OFF, the energy stored in the reactor 18 is supplied to an output in a route of a winding 21 from the negative electrode of an output smoothing capacitor 25 to the reactor 18, a diode 30 and the positive electrode of the capacitor 25. After the above operation is finished, the reactor 18 is reset by a controller 28.
