Types of Solar Power Systems Explained

Solar energy is slowly becoming a huge part of Indian households, and last year’s increased time at home has only cemented its growth. For example, financing in renewable energy projects and the decrease in solar module costs drove the solar prices in the country to an all-time low in 2020. In turn, this has encouraged more people … Read more

Switching Characteristics of IGBT

Switching Characteristics of IGBT is basically the graphical representation of behavior of IGBT during its turn-on & turn-off process. The turn-on time is defined as the time between the instant of forward blocking to forward conduction mode. Here, forward conduction means the device conducts in forward direction. Turn-on time (ton) is basically composed of two … Read more

VI Characteristics of IGBT Explained

VI characteristics of IGBT is the graphical relationship between collector current and collector-emitter voltage (VCE) for different values of gate-emitter voltages. It is basically a plot of collector current (IC) versus collector-emitter voltage for various values of gate-emitter voltage (VGE). VI characteristics of IGBT is also known as Static or Output Characteristics. Let us now … Read more

What is IGBT? – Construction and Working Principle

This article explains IGBT, its symbol, construction and working principle with relevant structure and circuit diagrams. What is IGBT? IGBT (Insulated Gate Bipolar Transistor) is a three terminal power switch having high input impedance like PMOSFET and low on-state power loss as in BJT (Bipolar Junction Transistor).
