The stacking design realizes 1600W output and super juce 100W gallium nitride fast charging and disassembly

2021-09-14

Overseas well-known charging accessories brand hyper juice recently raised a new 100W fast charging charger on indiegogo. This product is based on nano ganfast gallium nitride power chip and adopts stacking design idea. It not only supports its own foldable pin, but also integrates an AC socket. When in use, it will not occupy a two hole socket, and supports the stacking of up to 16 chargers.

Back to charging itself is also a bright spot. It is equipped with four output interfaces of 3c1a, which can meet the charging needs of four electronic devices at the same time; In case of single port output, port C supports blind plug output of 100W. At the same time, with the advantage of gallium nitride technology, it realizes small overall size and is convenient to carry out.

About the performance of this product, charging head network has shared relevant evaluation content not long ago. Today's article continues to share the internal disassembly of this charger.

This 100W 3c1a gallium nitride fast charge of super juice is based on the appearance of traditional charger and integrates innovative design. The addition of AC socket alleviates the shortage of socket in some application scenarios. At the same time, the design of multi port output also meets the needs of the current scenario of user multi device charging.

In terms of performance, based on gallium nitride technology, it has achieved a breakthrough in efficiency and volume, achieved small volume and great capability, supported any single C-Port 100W output and A-port 18W output, and is compatible with many mainstream charging protocols. No matter which interface the user connects, it can quickly charge the device and improve the use experience.

It is learned from the disassembly of the charging head network that the architecture of the charger is QR flyback topology + secondary voltage reduction, and the core device is the nano micro gallium nitride chip of AC-DC part. The characteristics of high frequency and high efficiency are an important prerequisite for realizing compact design. In addition, Zhirong's highly integrated step-down chip also simplifies the circuit design of the secondary step-down part. Even if four channels of independent step-down, it still occupies little PCB board. The materials of other components are also the mainstream lineup.

It should be noted that at present, the disassembled charger is an overseas version, so the power factor correction circuit is not set inside, which also frees up some internal space.
