Uninterruptible power supply based on ideal diode
Technical Field
The invention relates to the technical field of power electronics, in particular to an uninterruptible power supply based on an ideal diode.
Background
In the development process of the UPS, there are many technical obstacles, and one of the technical difficulties lies in the switching of the power supply, which is to ensure the stability of the power supply and achieve the purpose of fast switching. In low power applications requiring diodes, the forward voltage drop of the diodes may create supply margin problems or excessive power dissipation. Schottky diodes can reduce voltage drop, but schottky diodes are not available in many semiconductor processes. To avoid these problems, in the case of controlling the gate voltage of the transistor to operate as an ideal diode, a single transistor may be used instead of the diode. For very low power applications, so-called "ideal diode" circuits have fast forward drop recovery and fast direction recovery with low voltage headroom.
