Analog chip Analog chips mainly include power management chips and signal chain chips. Among them, the power management chip is a chip that is responsible for the conversion, distribution, detection and other power management responsibilities of electric energy in the electronic equipment system. It is mainly divided into AC-DC AC-DC conversion, DC-DC DC and DC […]
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 GTR saturation voltage is […]
Insulated Gate Bipolar Transistor (IGBT), also known as insulated gate transistor. Because it has a parasitic thyristor inside the IGBT, it can also be called an insulated gate thyristor. It is a new type of composite device developed in the mid-1980s. Because it combines the advantages of MOSFET and GTR, it has the advantages of […]
IGBT/power device The IGBT module is a modular semiconductor product that is packaged by IGBT (Insulated Gate Bipolar Transistor Chip) and FWD (Freewheeling Diode Chip) through a specific circuit bridge; the packaged IGBT module is directly applied to the inverter and the UPS is uninterrupted. Power supply and other equipment; IGBT module has the […]
Amplifier task is to amplify the weak electrical signal from the signal source (from the mixer in the professional audio system) to drive the speaker to produce sound. It can also refer to other devices that perform power amplification. The function of the power amplifier is to amplify the weak signal from the sound source […]
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 […]
