Abstract

PURPOSE:To shorten the responding time of a power converter circuit by shortening the switching time when a transistor is turned OFF. CONSTITUTION:When the output voltage of a control signal source 200 is low, a transistor 105 is OFF, a transistor 103 is ON, while a transistor 104 is not supplied with a base current since no current is flowed to a resistor 123 and becomes OFF. When the output voltage of the source 200 becomes high, the transistor 105 becomes ON, and the collector voltage is lowered. Accordingly, the base voltage of the transistor 103 is decreased, and the transistors 103, 102 become OFF, and the transistors 104, 101 become ON. Subsequently, when the output voltage of the source 200 is shifted from high level to low level, the current which drives the base of the transistor 101 is absorbed by the collector of the transistor 103, and the transisror 101 is turned OFF.

Since the conventional power conversion circuit is configured as described above and operates as described above, it has the following drawbacks.

That is, at the moment when the output voltage of the control signal source (200) is switched from a high level to a low level, the transistor (104)
) and (101) are both kept in the on state and are in a saturated state. These transistors therefore store excess carriers and remain on for their agile microsecond storage time even as the pace voltage of transistor (104) drops.

On the other hand, since the turn-on time of the transistor (LOA) and (102) is usually about several tens of nanoseconds, the transistor (LOA) and (102) turn on in an extremely short time compared to the several microseconds mentioned above, and as a result, the transistor (101) , (102) are in the on state when open for a few microseconds, and the series connection of the power supply (400), (500) is connected to the load (
300) can short circuit without passing t-, consuming unnecessary power and inducing noise voltages in the power supply due to the current flowing through the relatively large short circuit. Also, the load (30
0) may also be disturbed during switching. In addition, if an attempt is made to operate the transistor (101) in the active region instead of the saturation region in order to shorten the storage time, a disadvantage arises in that the power consumption p (increases).

Next, when the output voltage of the control signal source (200) increases, the transistor (ZOS) turns on and its collector potential decreases. Therefore, the pace potential of the transistor (103) decreases and the transistors (103) and (102)
is turned off, the pace current of the transistor (104) is supplied, and the transistors (104) and (101) are turned on. In this state, the output circuit ((400

Next, at the point in time when the output voltage of the control signal source (200) changes from high level to low level, the transistor (104)
, (101) is still in the on state due to an accumulation phenomenon, the transistor (103) is turned on, and the resistance (101) is turned on.
35) The current that was driving the pace of the transistor (lOt) through 't' is absorbed by the collector of the transistor (103), the voltage of the pace of the transistor (101) decreases, and the voltage of the pace of the transistor (lOl) and its emitter decreases. Since it is separated by a resistor (136), the voltage across this resistor is the voltage across the transistor (101).
It can be seen as an inverse junction between emitters and shortens the storage time of the transistor (101).
