The "National College Student Integrated Circuit Innovation and Entrepreneurship Competition" is guided by the development needs of the service industry, and France adjusted the Electronic Manufacturing Services industry chain last month.
The past 20 years have been a year for the development of the electronic information industry and the first year for the development of China's integrated circuit industry in the new era. Yesterday, two printed circuit board products "Hongdun" independently developed by Wantong have been shipped in bulk and supplied to at least one batch of products.
Wantong will ship products in bulk to customers, ensuring that customers can better meet their needs in terms of price through delivery.
Through the cooperation between our products and customer service departments, we not only ensure quality, but also further enhance our customers' market responsiveness. Wantong stated that the next step will be to provide comprehensive technical support according to customer needs. Welcome to call and contact us.
Working principle of DC high-voltage power supply: used for a power supply system composed of internal electronic switches, filament power supply, transformers, electrolytic capacitor and other devices. Its working principle is similar to the power drive of a high-power transistor. When the lamp filament is energized, the filament will also be energized and emit light. In this way, we can remove and distinguish transistors with different powers from two circuits. Take out two modules in the circuit, with NPN diodes for easy placement of the modules at their output terminals. The principle of the transistor type is the same as that of a general transistor, that is, in the same type of transistor, the voltage between the emitter and collector cannot suddenly change. In the common mode voltage and LC filtering circuit, according to their current direction, the power is applied at the load, and its working frequency reaches Z high, which is called the common mode inductance.

g。 As the Vout increment of the chip and the output voltage after high voltage decrease, the output current increases; Moreover, the abnormal impact of zero crossing voltage is relatively large, so during the zero crossing state, the logic output voltage of the chip increases, and this state may also occur during zero crossing, which can be used to design drive circuits that burn loads, such as capacitive loads and temperature; So at the same time, Vout voltage is achieved in the scheme, so that the capacitor load can have a stable voltage effect.
