IGBT basic application IGBT It is a device composed of a MOSFET (input stage) and a PNP transistor (output stage). It has the characteristics of small driving power and fast switching speed (control and response) of MOSFET devices, and bipolar device saturation. The voltage is reduced and the capacity is large (the power stage is […]
As one of the important high-power mainstream devices for power electronics, IGBT has been widely used in household appliances, transportation, power engineering, renewable energy and smart grid. In industrial applications such as traffic control, power conversion, industrial motors, uninterruptible power supplies, wind and solar equipment, and frequency converters for automatic control. The IGBT module […]
Why Does IGBT Module Desaturation Occur? An Engineer’s Guide to Protection In power electronics, a short-circuit is a catastrophic event. It can destroy an expensive IGBT module in microseconds, causing system downtime and costly repairs. The key to preventing this is effective desaturation protection. This is the fastest, most reliable method for detecting a short-circuit. This […]
A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals. Liquid crystals do not emit light directly, instead using a backlight or reflector to produce images in color or monochrome.[1] LCDs are available to display arbitrary images (as in a general-purpose computer display(NL6448BC33-70)) […]
A diode is an electronic device made of semiconductor materials (silicon, selenium, germanium, etc.). It has unidirectional conductivity, that is, when a forward voltage is applied to the anode and cathode of the diode, the diode is turned on. When a reverse voltage is applied to the anode and cathode, the diode is turned off. […]
IGBT module inverter circuit design for solar photovoltaic power generation (1) Solar photovoltaic power generation harnesses sunlight to convert solar energy into electrical energy using solar arrays, specifically PV module squares. The generated direct current (DC) is then transformed into alternating current (AC) through an inverter for user consumption. Traditionally, photovoltaic power generation systems employed […]
In the EMC design process, capacitors are the most widely used devices, mainly used to form various low-pass filters or as decoupling capacitors and bypass capacitors. Through practical data: In EMC design, proper selection and use of capacitors can not only solve many EMC problems, but also fully reflect the advantages of better results […]
