Synchronous rectification is a new technology that uses a special power MOSFET with very low on-state resistance to replace the rectifier diode to reduce the rectification loss. It can greatly improve the efficiency of DC/DC converters and there is no dead voltage caused by Schottky barrier voltage. Power MOSFET is a voltage controlled device, and its volt-ampere characteristics are linear when it is switched on.
Principle of synchronous rectifier circuit synchronizationA current circuit is a circuit that uses a method of synchronizing with the input voltage or current to achieve rectification. It usually consists of a converter and a rectifier. The converter can convert alternating current into direct current, while the rectifier can remove the instability in the output voltage or current. This method improves efficiency and can be used to control the amplitude and phase of current or voltage.
Synchronous rectification is to change the secondary side rectifier diode to use MOSFET rectification to improve efficiency.
When using a power MOSFET as a rectifier, the gate voltage must be synchronized with the phase of the voltage being rectifiedIn order to complete the rectification function, it is called synchronous rectification. PS7516 and PS7616 are lithium battery booster output 5V1A, 2A synchronous rectifier booster classic IC, FP6717, FP6716 is also lithium battery booster output 5V3A, 5V2A leader.
Synchronous rectification technology is a kind of power conversion technology, which can realize effective power control and optimize conversion efficiency by controlling circuit switching, optimizing circuit topology and current sampling. Compared with traditional non-synchronous rectification technology, synchronous rectification technology can control the current more accurately and make full use of the batteryEnergy storage to reduce energy loss and conversion losses for greater energy efficiency and longer battery life.
Xiao Xiao Er Hao. The outdoor power supply has good quality and performance, stable output, safe and reliable, and its portability is also one of its advantages, small size, light weight, and can be easily carried. The internal cell of the mobile power battery uses a lithium battery, and the chemical properties of lithium are more active and easy to burn chemical elements, so the electricity is good.
Mobile power supply 220The volt junior is better. Electric small second is one of the most famous outdoor power supply brands in China, with stable product performance and good reputation.
