▋ Market Analysis of DC Brushless Electric Tools
Overview of the electric tool market:
In recent years, the electric tool industry has shown a rapid development trend. For many years, China's electric tools have mainly been exported, accounting for 85% to 90% of the total production, and the domestic market sales account for 10% to 15% of the share. Despite the large export of domestic electric tools, the market share of domestic electric tools still exceeds 90% in the domestic market. In the foreign power tool market, China's manufacturing proportion continues to expand, accounting for 90% of global production, making China a major exporter of power tool products and a global power tool production base. The industry has enormous development potential. Professional electric tools for industries with high technological content and strict performance requirements in China still have a large latent market in European and American countries. At present, in industrial countries in economically developed regions, such as Germany, Britain, the Netherlands, France and other countries in Europe, the United States, Canada in North America, Japan in Asia and other countries, the use of electric tools in home homework is very common, accounting for about 50% to 70% of the total output. China's electric tool products have occupied a large share of the domestic electric tool market in the above countries and regions. Based on the sales revenue of the electric tool market in the past five years, it is predicted that the sales revenue of China's electric tool industry will reach approximately 128.3 billion yuan by 2018, indicating a significant potential for market demand growth.
Electric tools are divided into three types:
1．Hand-Held Motor-Operated Electric Tools
2．Mobile electric tools
3．Garden electric tools
According to the power supply method, it can be divided into two types:
1．High voltage AC power tools based on AC power supply
2．Low voltage DC electric tools powered by batteries (battery voltage not exceeding 75V)

—— IGBT ——
▋ IGBT（1200V-1350V）
The new generation IGBT of Ncepoower adopts Trench Field Stop technology with a groove structure, which greatly increases the power density of the device. Through the advanced Ultra Thin Wafer Process, the Field Stop structure is used at the extreme of chip collection, significantly reducing the saturation on voltage drop (Vce (sat)) and off loss (Eoff) of the device compared to the previous generation products, The power loss of the device (the sum of conduction loss and switching loss) has been reduced by 33%, and is equipped with an independent constant voltage fast recovery diode (FRD), making it suitable for various soft switching applications such as electromagnetic heating.
The new generation of 1350V product series elevates the breakdown voltage of devices to new standards and ensures that products still have stable and consistent electrical parameters and firm reliability in harsh environments. At the same time, the new generation IGBT series products adopt advanced carrier control technology, which enables devices to achieve lower power loss while also having stronger avalanche and short-circuit current tolerance. Compared with the previous generation products, the short-circuit current tolerance of the new generation FS IGBT series products has increased by 50%, reaching the industry-leading level.

▋ Mobile Phone Fast Charging
QC3.0：
We use an algorithm called Intelligent Negotiation for Optimal Voltage (INOV), which supports dynamic adjustment of working voltage from 3.6V to 20V in steps of 200mV. Compatible platforms include Qualcomm Snapdragon 820, 620, 618, 617 and 430, and Backward compatibility QC2.0 and QC1.0 devices, which can be used on USB Type-A interface, USB micro interface and USB Type-C interface.
Fast charging principle:
By replacing the traditional 5V/1, 2A charger mode with low voltage and high current, the effect of high current accelerated charging is achieved. And adjust the input voltage within a controllable range of voltage to achieve the effect of increasing charging power, thus forming fast charging.
