The switching power topology is not unfamiliar to the electronic engineer. There are about 14 kinds of basic topology maps, each of which has its own characteristics and applicable occasions. In addition, more topology composition is also the combination or deformation of these basic types. The following two are more c……

IGBT, also known as the insulating grid bipolar transistor, is a composite full -control voltage driving power semiconductor device composed of bipolar crystal tube (BJT) and insulating grid effects transistor (MOS). Its input is MOSFET, and the output is a PNP transistor. Therefore, it can be regarded as the Dallingto……

What is topology? The so -called circuit topology is the connection method of power devices and electromagnetic elements in the circuit, and the design of magnetic components, the design of the closed -loop compensation circuit, and the design of all circuit components depends on topology. The most basic topology inclu……

The field effect tube is a voltage control device. The distance between the leakage source of the field effect tube is equivalent to a resistor. Therefore, the field effect tube used in the circuit usually plays the effect of voltage control resistance, that is, the voltage control current. Specifically, one is to make……

After making the first 10,000 yuan public welfare investment decision and the payment, Wei Ge (Huang Wei, general manager of Henglitai Technology), who had just arrived in Shenzhen Huaqiang Bei, began to expand. In the high -end wine bureau of 500 yuan in the Wangjiang Tower group, try how much garlic can be installed ……

On the afternoon of December 16, the Fourth Session of the Second Council of the China Information Industry Chamber of Commerce Electronic Component Application and Supply Chain (ECAS) was held in Shenzhen. Zhou Jiguo, chairman of the branch, Feng Wei, Wang Yucheng, Ye Deren, Liu Hongbing, Zhu Yeqing, Li Honghui, Chen ……

P -channel enhanced field effect tube's in diversion conditions are that the gate potential is lower than the drain potential. The more lower the grid potential is lower than that of the drain potential, the more you turn it on. Generally, it can be fully turned off than 15V less than 15V. If the pressure difference is……

The analog signal refers to the continuous changing electrical signal. The simulation circuit is the basis of electronic circuits. It mainly includes amplifier circuit, signal operations and processing circuits, oscillation circuits, modulation and demodulation circuits and power supply. The following is our common ana……
