50W, 110W ultra-flash mini charger: portable and more compatible
OPPO’s first 50W Ultra Flash Cookie Charger and 110W Ultra-Flash Mini Charger provide a more portable experience, especially with the ultimately lightweight body, on the basis of ensuring efficient charging. 50W ultra-flash cookie charger pioneer runway-type ultra-thin shape, large area application of multi-arc curve design, the whole like cobblestone-like round, thickness of only 10.5mm, with folding pin design, easy to adapt to the daily storage, easy to place in shirts, jeans pockets, ultra-small and unburdened. The 50W Ultra Flash Cookie Charger is compatible with SuperVOOC and VOOC Flash, supporting 27W PD, 18WQC, and 50W PPS and other industries, such as universal fast charge protocols for fast charging for mobile phones, tablet computers and other devices. With its innovative look, sophisticated hardware stacking and advanced underlying technology architecture, THE OPPO 50W Ultra Flash Cookie Charger breaks the long-standing charger design paradigm and opens up new directions for mobile phone fast charging technology.
High power adaptation to its miniaturization must break through the traditional scheme, the traditional charger needs to rely on the built-in electrolytic capacitor storage capacity to achieve a stable power output, but with the increase of power, electrolytic capacitance volume needs to increase accordingly, coupled with the generally thicker traditional transformer, resulting in the traditional scheme under the high power charger volume remains high.
In response to the electrolytic capacitor volume problem, the OPPO flash charge team designed a new generation of revolutionary technology architecture: electrolytic-free capacitor design, and the industry for the first time introduced a smaller aviation-grade device – clamp diodes, absorbing up to 250KW of surge impact, so that the charger safely supports the entire grid voltage. After the electrolysis capacitor is removed, the current that the charger enters into the phone is a 100 Hz pulsed direct current, for which the 50W ultra-flash cookie charger uses a new charging technology, pulse charging. Compared to conventional charging methods, pulse charging is eliminated due to the presence of a very short charging gap, the polarization of the battery is eliminated, the battery is less loss and the temperature changes are smaller.
For traditional transformer volume issues, 50W ultra-flash cookie chargers have been upgraded from conventional transformers to high-frequency flat-panel transformers, reducing the vertical space by 50%. The introduction of the high frequency of nitride argon switch, so that the transformer single energy storage requirements become smaller, and thus reduce the volume of the transformer, OPPO self-developed ACF (ActiveClamp Flyback) control architecture to achieve zero voltage (ZVS) zero current (ZCS) switch, switch loss infinitely close to 0.
Building on the 50W Ultra Flash Cookie Charger, the 110W Ultra Flash mini charger achieves high-efficiency power conversion and temperature-up control with a ground-breaking two-stage architecture, with innovative laminated laminate stacking and extreme structural shell design that also controls the thickness at 12mm. In addition to fully compatible with SuperVOOC and VOOC, the 110W Ultra-Flash mini charger also supports 110WPPS, 65W PD, and 36W QC, covering the mainstream laptop, tablet and mobile fast charging protocols on the market.
