In the At the next generation OPPO super flash charging conference this afternoon, the company released some charging solutions. The Chinese manufacturer revealed it 125W super flash charging as well as 65W AirVOOC wireless charging technology. In addition, Oppo also released two chargers. These include the Charger 50W super flash and the Mini charger 110W super flash.
For the first time, Oppo said it was able to increase the power of the tiny charger to exceed 100W. According to the company, he used one electrolyte capacitor design, pulse charging and high frequency flat transformer technology to reduce the number and volume of components in the charger. This charger places great emphasis on breaking the power and performance limits of high power chargers. Oppo had to use one pioneering two-stage architecture to achieve high-efficiency power conversion and temperature control.
According to reports, the USB-C interface supports mainstream charging protocols such as VOOC, PD, PPS and QC. also supports up to 65W PD & SuperVOOC, 110W PPS, 36W QC and 30W VOOC. With these, this charger can charge most electronic devices on the market. That obviously includes OPPO mobile phones, PD / QC-supported smartphones, and PD-supported laptops.
Mini 50W and 110W Flash chargers use GaN (Gallium Nitride) to conduct high voltages and currents in small size. Unfortunately, the company did not announce the price and availability of this device.
How the small charger Oppo 110W is extremely small
First, we need to know that the 110W mini flash charger is built on the combination of structural elements and solid constructions. This ultimately minimizes its size to just 35.76 cm ³ – similar to the size of a regular 18W charger. Oppo’s 110W mini-flash charger was a breakthrough in the size and performance of high-power adapters. However, how did Oppo do it? Here are some points to take a look at what Oppo really did
- Eliminate electrolytic capacitors and use aviation quality fixing diodes, reducing the size of the motherboard by 52%.
- It introduced gallium nitride high frequency devices instead of silicon-based MOSFETs to meet the needs of low volume high frequency switching. This ensured that the flat screen transformers were diluted to 8 mm.
- The new Active Clamp Flyback topology control structure “cleans” the voltage and current before and after the action of the switch, to achieve zero electricity
Also note that the Oppo 110W super flash charger is simply an upgrade of the 50W mini SuperVOOC. Thus, the above points also apply to the 50W mini SuperVOOC
