In today's society, with the rapid development of power technology and the increasing demand for equipment in the medical industry. After all, medical devices are electronic devices that come into direct contact with the human body. Firstly, the performance and accuracy of electronic devices are highly required, and the safety of the power supply equipment used in electronic devices must comply with national regulations. In the medical industry, there are many electronic devices, such as ultrasound X-rays, fetal monitors, and life monitors, that come into direct contact with the human body. When using these devices, it is necessary to avoid contact and radiation between the device and the human body. Therefore, there are strict requirements for the design and use of medical power supplies.Medical power supply is a power supply device that provides power security for medical equipment and institutions. Due to the high requirements of medical equipment for power quality, power supply re...

LED driver power supply is a type of power supply, which is just a specific type of power supply. This type of power supply drives LED lighting with voltage or current, and is one of the reliable power supply devices. How to judge the quality of LED driver power supply? In response to this issue, this article will provide a detailed introduction for everyone.High power LED driver power supplyHow to judge the quality of LED driver power supply?1. Driver chip: ICThe center of the LED driver power supply is the IC, and the quality of the IC directly affects the entire power supply. The driving ICs of large factories are all acquired by Jingyuan in search of large packaging factories to package; The driving IC skills of small factories are to directly copy the driving planning plan of large factories and find small packaging factories to package, which cannot guarantee the consistency and stability of the entire batch of ICs, and then cause the driving power supply to mysteriously fail af...
A switching power supply is a type of power supply that utilizes modern power electronics technology to control the time ratio of switching on and off, and maintain a stable output voltage. Switching power supplies are generally composed of pulse width modulation (PWM) control ICs and MOSFETs. With the development and innovation of power electronics technology, switch mode power supply technology is also constantly innovating. At present, switching power supplies are widely used in almost all electronic devices due to their small size, lightweight, and high efficiency, and are an indispensable power supply method for the rapid development of the electronic information industry today. So what are the PCB design specifications for switching power supplies?PCB design specifications for switching power supplies:1. Establish component parameters from schematic diagram to PCB design process ->Input schematic network table ->Design parameter settings ->Manual layout ->Manual...
Quasi resonant switching power supply is a topology structure of switching power supply that combines the characteristics of resonance and switching power supply to achieve high efficiency and low loss energy conversion. During operation, quasi resonant switching power supplies use resonant circuits to reduce the losses of switching tubes and improve overall efficiency. Its working principle is similar to traditional switching power supplies, but to a certain extent, it adopts resonance technology.Quasi resonant switching power supplyThe main characteristics of quasi resonant switching power supply include:Resonance characteristics: Compared with traditional switching power supplies, quasi resonant switching power supplies use resonant circuits to achieve the switching tube to turn off at zero or low voltage, thereby reducing switching losses and EMI (electromagnetic interference).High efficiency: By reducing the loss of switching tubes, quasi resonant switching power supplies can ach...
There are several common types of high-power battery chargers:90W Battery Charger1.What is a high-power battery charger?A high-power battery charger is a faster and stronger charging device than a regular charger, capable of charging devices such as smartphones and tablets faster through higher current output. However, due to the greater heat generated by high-power battery chargers, safety issues are also more likely to attract attention.2. Common types of high-power battery chargers● Fast chargingFast charging is a widely used high-power battery charger on the market, with mainstream fast charging protocols including QC, FCP, VOOC, Dash Charge, etc., which can charge devices in a short period of time. However, due to compatibility issues with different protocols, it is necessary to choose chargers that support the corresponding fast charging protocol for different brands and models of devices.● PD chargingPD charging is currently the latest fast charging standard, supporting higher...
