    There are many magnetic devices used in switching power supplies, among which the commonly used soft magnetic devices are: the main transformer (high-frequency power transformer) as the core device of the switching power supply, common mode choke, high-frequency magnetic amplifier, filter choke, spike signal suppressor, etc. Different devices have different performance requirements for materials. The table shows the performance requirements of various devices for magnetic materials. (1) High frequency power transformer The size of the transformer core depends on the output power and temperature rise. The design formula of the transformer is as follows: P=KfNBSI×10-6T=hcPc+hWPW Among them, P is the electric power; K is the coefficient related to the waveform; f is the frequency; N is the number of turns; S is the iron core area; B is the working magnetic induc...

    First, let's talk about the definition of the inductor quality factor Q. The Q value is the main parameter for measuring inductor devices. It refers to the ratio of the inductive reactance to its equivalent loss resistance when the inductor works under an AC voltage of a certain frequency. The higher the Q value of the inductor, the smaller its loss and the higher its efficiency. The quality factor Q is an important parameter that reflects the quality of the coil. Improving the Q value of the coil can be said to be one of the key points to pay attention to when winding the coil. So, how to improve the Q value of the winding coil? The following are specific methods: 1. According to the working frequency, select the wire of the coil  Inductor coils working in the low frequency band are generally wound with insulated wires such as enameled wire. In circuits with oper...

    Real-World Applications of IEC Inlet EMC Filters IEC inlet EMC filters are widely used in various industries and applications to ensure electromagnetic compatibility (EMC) and protect electronic devices from electromagnetic interference (EMI). Here are a few examples of how these filters are used in real-world scenarios: Industrial Machinery In industrial settings, EMC filters are essential for protecting sensitive electronic components and control systems from interference. IEC inlet EMC filters are commonly used in industrial machinery such as CNC machines, robotic systems, and manufacturing equipment. By filtering out unwanted noise and spikes in the power supply, these filters help ensure reliable operation and prevent costly downtime[1][3].  Medical Equipment Medical devices, such as diagnostic imaging systems, patient monitors, and su...
