Module protection-overheating protection heat dissipation is an important factor that affects whether the module can work safely. Good heat dissipation conditions can not only ensure the reliable operation of the module, prevent the module from overheating, and improve the current output capacity of the module. In the ……

I believe at this moment, you and I have been waiting for too long. After several versions of public beta, you finally released the official version of the professional version of the client! Of course, it is still "free"! Lichuang EDA will implement the free domestic PCB design tools to the end, and determines to prov……

Module protection-overvoltage protection of the transmission of the crystal tube is extremely poor. When the reverse voltage of the component exceeds its reverse breakdown voltage, even if the time is short, the component will be damaged by reverse breakdown. If the DC voltage exceeds the positive direction voltage of ……

Testing is more convenient. The following is a common problem for the first time, which may be inspired by you. The module has no current or voltage output when regulating a given signal, but the given signal and the 12V power supply applied are normal. Processing: You need to reset the module. When the constant voltag……

The characteristics and application of the constant voltage pressure module of the constant current gates 1. Introduction In modern industrial production, the crystal tube has been widely used due to its mature technology, large current, and high voltage. In the automatic control system composed of a crystal tube, many……

Pressure) can no longer solve the problem of heat dissipation. Therefore, new requirements have been put forward on the heat conduction insulation material between the heat dissipation backplane and the chip. At present, such materials used by the electricity and electronics industry at home and abroad are generally ce……

What is the difference between the regulation function of the AC module and the transformer? The transformer can isolate the load from the power grid to the equal amount of the equal amount of transmission according to the set variable ratio; the AC module is not isolated from the grid, and only the power grid voltage ……

Since 2021, the new crown epidemic has been continuously raging. However, with the efforts of all colleagues, Shenzhen Jinhang Standard Electronics Co., Ltd. (www.bds666.com) has achieved the goal of double performance. Golden Airlines's brother company Sarko Micro Semiconductor (www.slkormicro.com) Co., Ltd., the turn……

Module protection-overcurrent protection If you want to get more secure overcurrent protection, it is recommended that users give priority to choosing modules with built-in overcurrent protection functions. In addition, you can also use external fast purse, fast overcurrent relay and sensor. Fast melting is the simples……

What is IGBT? IGBT is an English word Insulated Gate Bipolar Transistor. Its Chinese means the insulation grid bipolar crystal. In terms of function, IGBT is a circuit switch. Its advantages are voltage control, low saturation voltage drop and high resistance. Used for high voltage for dozens to hundreds of volts, and ……

How does the IGBT module conduct? The structure of IGBT silicon wafers is very similar to the power MOSFET. The main difference is that IGBT adds the P-prolapse and the N buffer layer (NPT-non-pass-IGBT technology does not increase this part). A MOSFET drives two bipolar devices. J1 knots are used between the P and N r……

What is the relationship between the switch loss and performance of the IGBT module? In the development of IGBT, power switching devices are required to reduce loss, improve efficiency, and improve performance. The loss of the switching component can be divided into two categories, one is the device loss of the normal ……
