DC-DC Adapter mainly refers to the circuit that manages battery and electric energy, and is a key device in electronic equipment. According to the function classification, the main functions of the power management chip include battery charge and discharge management, monitoring and protection, power form and voltage and current conversion (including DC/DC conversion and other forms).
How does a DC-DC Adapter work?
What are the features of DC-DC Adapter?
What are the working steps of the DC-DC Adapter?
DC-DC Adapter is achieved by using semiconductors such as insulated gate bipolar transistors (IGBTs), power metal oxide semiconductor field effect transistors (MOSFETs), thyristors or other power-controlled semiconductor devices as well as diodes and LC circuits. It should be noted at this point that the above gated semiconductors operate as switches. These controlled semiconductor devices operate only in the on state or blocked state. If a gating pulse is applied to the gate of an IGBT or MOSFET, they will switch to the on mode and will remain in this state until the end of the gating pulse interval.
The DC-DC Adapter is a device that reduces 110 or 220 volt AC household current and converts it to DC in order to power electronic devices, appliances or some other electrical equipment. It consists of a transformer in a box with a wall plug on one end and a power cord on the other. The DC-DC Adapter has a switch on the box that allows the user to select the output voltage, usually between 1 and 20 volts, and connected to the output is a series of diodes for converting AC current to DC. The universal power supply comes with a variety of output jacks, each designed to fit the input of a device operating at one of the selected voltage settings.
DC-DC Adapter is a power supply that uses modern power electronics technology to control the time ratio of switching transistors on and off to maintain a stable output voltage. The switching power supply is generally composed of a pulse width modulation (PWM) control IC and a MOSFET. In the switching voltage regulator circuit, when the switch is in the on-off state, the tube works alternately in the cut-off and saturated states. From the knowledge of the triode, when the triode works in the cut-off state, although the voltage drop of the tube is large, but The current flowing through the tube is almost zero; when the tube works in a saturated state, the current flowing through the tube is large, but the voltage drop across the tube is approximately zero. Therefore, when the regulating tube works in the switching state, its own power is extremely low. Under the same output power, the efficiency of the switching regulated power supply is higher than that of the series regulated power supply, generally reaching about 85%. Due to its low consumption, sometimes even the heat sink is not used, and the switching power supply generally does not have a bulky power frequency transformer, which greatly reduces its weight and volume.
