Abstract

PURPOSE: To obtain a rectified output with a high responce property and no ringing, by turning on the rectifying diode and off the switching transistor each when the transformer output is positive and then turning off the diode and on the transistor each when the transformer output is negative respectively.
CONSTITUTION: The transistor TRQ2 functions as a switching TR and is turned on and off alternately along with the rectifying diode D2. accordingly, the diode D2 is turned on when the output pulse of the transformer T1 is pulse to obtain the pulse from which the forward voltage Vf is subtracted at the output. In this case, the diode D4 is also turned on through the resistance R, and thus the TRQ2 becomes off-bias with the emitter and the base set at nearly the same potential. And the TRQ2 is cut off. Then both the diodes D2 and D4 are turned off when the output pulse of the T1 is minus. Then the base current is given to the TRQ2 by the resistance R, and accordingly the TRQ2 is turned on. In such way, a rectified output can be obtained with a high response property and no ringing.
