The circuit diagram is one of the basic skills that electronics engineers must learn. This article combines the classic integrated circuit data related to regulated power supply, DC to DC conversion power supply, switching power supply, charging circuit and constant current source to provide engineers with the most fresh circuit diagram reference materials. First, […]
The drive circuit of the IGBT must have two functions: one is to achieve electrical isolation between the control circuit and the gate of the driven IGBT; the other is to provide a suitable gate drive pulse. There are many driving circuits for IGBTs, and the driving circuit for discrete components is simple and inexpensive. […]
Temperature control is one of the key factors for the effective operation of MOSFET or IGBT module. Although some MOSFETs are equipped with an internal temperature sensor (body diode), other methods can also be used to monitor temperature. The semiconductor silicon PTC thermistor can perform current control well, or the platinum-based or niobium-based (RTD) resistance […]
On August 24, ADI officially announced that the acquisition of Maxim by ADI has obtained anti-monopoly approval from the State Administration for Market Regulation of China! So far, the transaction has obtained all necessary regulatory approvals. ADI and Maxim expect that the transaction will be completed on or about August 26, 2021 after meeting […]
First, what is IGBT? IGBT (Insulated Gate Bipolar Transistor), insulated gate bipolar transistor, is a composite fully controlled voltage-driven power semiconductor device composed of BJT (bipolar transistor) and MOS (insulated gate field effect transistor), and has MOSFET The advantages of both the high input impedance and the low turn-on voltage drop of the GTR. The […]
1. What is an IGBT? One of the most important components in power electronics is the IGBT. The so-called IGBT (Insulated Gate Bipolar Transistor) is a composite full-regulated-voltage-driven-power semiconductor device composed of BJT (Bipolar Junction Transistor) and MOS (Insulated Gate Field Effect Transistor), which has its own The feature of shutdown. To […]
integrated circuit Integrated circuit (Integrated circuit) is a kind of miniature electronic device. It uses a certain process to interconnect the transistors, resistors, capacitors, inductors and other components and wiring required in a circuit on a semiconductor substrate, and then encapsulate them in a tube. Inside the shell, a miniature structure with the required circuit […]
Two conductors close to each other sandwich a non-conductive insulating medium between them, which constitutes a capacitor. When a voltage is applied between the two plates of a capacitor, the capacitor will store charge. The capacitance of a capacitor is numerically equal to the ratio of the amount of charge on one conductive plate to […]
Transistor is a solid semiconductor device (including diodes, triodes, field effect transistors, thyristors, etc., sometimes referred to as bipolar devices), which has multiple functions such as detection, rectification, amplification, switching, voltage stabilization, signal modulation, etc. . As a variable current switch, the transistor can control the output current based on the input voltage. Unlike ordinary […]
1. Detect a small capacitor below 10pF. The capacity of a fixed capacitor below 10pF is too small. Use a multimeter to measure it. Only qualitatively check whether it has leakage, internal short circuit or breakdown. When measuring, you can use the multimeter R×10k block. Use two metal meter bars to connect the two pins of […]
