Difference between IGBT and MOSFET

IGBT and MOSFET are  Power Transistor both are voltage controlled device with isolated Gate.

IGBT- Insulated Gate Bipolar Transistor.

  1. IGBT suitable for high voltage, low frequency application.
  2. IGBT has additional p-n junction and giving it properties of Both MOSFET and BJT. 

     
  3. IGBT terminal- Gate, Collector, Emitter.
  4. Available Voltage rating of IGBT is up to 1400 Volts.
  5. IGBT can be used frequency rating up to 20 kHz.
  6. IGBT required more time to turn off.
  7. It is highly tolerant to Electrostatic discharge.  
  8. IGBT has lower forward voltage drop.
  9. IGBT has great capacity of handling transient voltage and current.
  10. IGBT cost is more.

MOSFET- Metal-Oxide Semiconductor Filed Effect Transistor 

  1. MOSFET suitable for low voltage and high frequency application.
  2. MOSFET doesn't have a p-n junction
  3. MOSFET terminal- Gate, Drain, Source.
  4. Available Voltage rating of MOSFET is up to 600 Volts.
  5. MOSFET can be used frequency rating up to 50kHz.
  6. MOSFET required less time to turn off.
  7. Electrostatic discharge may harm MOSFET.
  8. MOSFET has higher forward voltage drop.
  9. MOSFET doesn't have capability to handle transient. It may disturbed working or damage MOSFET.
  10. MOSFET is low cost device.

Do you know meaning of alphabets written on MCB just before the current rating?

What is MCB? MCBs are automatic switches that automatically turn off the power supply when it detects an excessive current. Earlier, this action used to be done by fuses. Though fuses have one disadvantage, they need to be replaced every time there is a short circuit. An MCB, on the other hand, can be manually restarted and is more durable. Types of MCB MCBs are installed in spaces depending on the need of the appliance. Hence, you will find multiple MCB types that can be used for a range of purposes. The most popular MCB types are A, B, C, D, K and Z. Of these, the most commonly used are B, C and D. These categories are often based on their trip curve or tripping capacities. Type A MCB trips off the circuit when the current exceeds 2-3 times the actual current rating. A type MCB – Miniature Circuit Breaker is highly sensitive to the short circuit, and hence we can find its application in the manufacturing of semiconductors. Type B  These are often used in residential properties or...

Shunt capacitor and applications.

Image
  Shunt Capacitors and it's applications Shunt means parallel. In simple words, the capacitor is connected in parallel with a load or power supply is called shunt capacitor. The series and parallel combination of a no. of shunt capacitors is called shunt capacitor bank. So shunt capacitor is not a special device. It is a normal capacitor only, it is called a shunt capacitor because of its parallel connection with load. Application of Shunt Capacitor: 1-Electrical Power Distribution System. In an electrical power distribution system, shunt capacitors are used. Generally, shunt capacitors or shunt capacitor banks are connected in parallel with each feeder to improve the power factor of that particular feeder. 2-Electrical Transmission line.  Shunt Capacitor bank also used in long-distance transmission lines. In long-distance transmission lines (above 66KV) shunt capacitor banks are used to increase the electrical power transfer capability without extra conductors. The shunt capa...

Solar Panel and it's types

Image
Solar panels  are those devices which are used to absorb the sun's rays and convert them into electricity or heat .  Solar panel is actually set of photovoltaic modules, mounted on a structure supporting it. The Benefits of Solar Panels Solar panels make it possible to live off-grid. It is both a clean and a renewable source of energy. Low maintenance cost. Once a system has paid for its initial installation costs, the electricity it produces for the remainder of the system's lifespan, which could be as much as 15-20 years depending on the quality of the system, is absolutely free! Types of Solar Panels The solar panels can be divided into 4 types, Monocrystalline solar panels Polycrystalline solar panels Passivated Emitter and Rear Contact cells (PERC) solar panels Thin-film solar panels 1- The monocrystalline solar panels  They are also known as the single crystal panels. They are made from pure silicon crystal which is sliced into several wafers forming cells. These wa...
