A DC-DC Adapter is an interface converter that allows a hardware or electronic interface to be connected to other hardware or electronic interfaces. In a computer, adapters typically exchange adaptation information built into a card-in-card that can be inserted into a slot on the motherboard with the processor and the devices supported by the adapter.
What is the workflow of a DC-DC Adapter?
What do we need to pay attention to when using DC-DC Adapter?
What is the difference in the working method of DC-DC Adapter?
The transformer has an input and output coil, both wound on a central core, and the ratio of input voltage to output voltage depends on the relative number of turns of the two coils. switches on the DC-DC Adapter vary the output voltage by changing the position of the connections to increase or decrease the number of output coils. A diode converts current from AC to DC by passing current in one direction while canceling the current in the return direction.
While DC-DC Adapters can be used to power a variety of different devices, there is no one size fits all. Before purchasing a laptop power supply or a power supply for sensitive electronic equipment, the purchaser should check its voltage rating range and the output jack that comes with it to make sure it will not work. The power supply output current rating should also be the same as the device being used.
Reverse polarity
Higher voltage adapters than the device rating
The following conditions can damage your power cord or adapter.
Reverse polarity
Current adapters below the device rating
The following may not cause damage, but the equipment will not function properly.
Adapters with a voltage lower than the device rating
Current adapter higher than the device rating
A brief description of electrical terms
Each DC-DC Adapter is specifically designed to accept a specific AC input (usually the standard output of a 120 V AC outlet in your home) and convert it to a specific DC output. Likewise, each electronic device is specifically designed to accept a specific DC input. The key is to match the DC output of the adapter to the DC input of the device. Determining the output and input of the adapter and the device is the hard part.
1. The first DC-AC common ground method is the simplest common ground scheme, with anti-static and electromagnetic interference functions, but with poor safety. If the ground wire in the power supply line is broken, when the leakage fault occurs at the AC terminal, the DC output terminal will also be charged;
2. The second way of co-locating will not cause the first problem. But the DC part has no antistatic protection function;
3. In the third common ground scheme, the DC-AC common ground connection test has an impedance of 1K or 1M ohms, indicating that there are isolation components in series between the two grounds, which can isolate and weaken the alternating current, which is also used by regular power adapters now. The standard grounding method solves the defects of the above two schemes very well.
