Dc charging pile display chip DC-DC converter
Main component
Concept:
DCDC Converter, full name DC-DC Converter (DC-DC converter), is a power conversion device, its core function is to convert one DC voltage to another DC voltage. This conversion is very important in electronic devices, communication devices and other fields, especially in DC charging pile display chips, where DCDC converters are used to provide a stable power supply.
Function:
The main functions of DCDC converters include:
Voltage conversion: The high voltage of the power battery pack is converted to a constant low voltage, such as 12V, 14V or 24V, to supply the electrical equipment and charge the auxiliary battery.
Power management: In electronic devices, DCDC converters contribute to power saving, miniaturization and lightweight of devices by efficiently converting voltage.
Stable power supply: Ensure that electronic devices such as DC charging pile display chips can operate stably and provide the required DC voltage.
Working Principle:
The working principle of the DCDC converter is mainly based on the following aspects:
Inductive voltage volt second balance law: Under steady state operation, the forward volt second (voltage times time) on the inductor is equal to the reverse volt second, that is, the energy stored by the inductor is balanced when the switch tube is on and off.
Switch control: DCDC converter adjusts the current flow to achieve voltage conversion by controlling the high-speed switching action of the switching tube (such as MOSFET, IGBT, etc.).
Energy storage and release: When the switching tube is on, the inductance stores energy; When the switching tube is closed, the inductor releases energy and continues to flow through the diode to maintain the stability of the output voltage.
Output voltage control: The output voltage is compared with the reference voltage through the divider resistor to form a feedback. When the output voltage is lower than the reference voltage, the oscillation circuit is triggered to work, and the MOS tube is controlled, and the reverse is cut off.
Sum up
DCDC converter realizes efficient and stable voltage conversion through these principles, and provides necessary power supply for electronic devices such as DC charging pile display chip.
DC CHARGING PIlE SERIES
DC charging pile is an efficient charging facility for electric vehicles, which uses direct current (DC) to directly charge the vehicle battery, significantly reducing the charging time. Compared with traditional AC charging piles, DC charging piles are able to provide higher power output and can usually charge an EV to 80% of its capacity in 30 minutes, providing users with a convenient charging experience.
