But when we use electronic digital entertainment products, we will also encounter electronic equipment strikes. The plug-in standard authentication power adapter needs the power adapter to charge it at this time. Plug-in standard certification power adapter also has a situation that we cannot foresee, that is, travel. Suddenly, the shooting equipment is out of power. If there is a charger, what should we do? At this time, we need to prepare a convenient, fast, safe, and space-saving mobile power supply for our things when we go out.
The more important issue may be the current data security, sudden automatic protection, and stopping work is a very scary thing for computers, especially for many friends who don’t use batteries. In some cases, unexplainable restarts of the computer are also related to this. For the original power supply, the manufacturer knows which load to connect, so it is easy to calculate the nominal voltage and rated current of the power supply.
Plug-in certification, the power adapter and the adapter are power switches, and are controlled by the high-frequency switching circuit. As long as the adapter is not a current regulated power supply voltage, the wall plug adapter switching power supply certification has a floating function, and the voltage becomes larger with a smaller current.
However, if non-original equipment adapters, such as general-purpose transformers, etc., the above issues cannot be seriously considered, then users can only try to find ways to obtain them from compatible electrical parameters. However, the internal resistance of each adapter has a different tolerance, the nominal voltage can vary, and the variation range of the rated current output voltage can be different, even if the output ripple coefficient is not small enough.
The present invention relates to a plug-in type medium gauge power adapter power adapter (PIC). It is an integrated circuit that integrates a high-voltage power supply device, a signal processing system, and a peripheral interface circuit protection circuit detection and diagnosis circuit, etc., generally divided into There are two kinds of smart power integrated circuits (SPIC) and high-voltage integrated circuits (HVIC), but with the development of PIC, plug-in and wall-type IC power adapters are both in working voltage and device structure (vertical or horizontal).
