What are the fundamental requirements of gate drive ICs?


Description : Explain MOSFET gate drive circuit and totem pole configuration.

Answer : MOSFET gate drive circuit: The turning on and turning off of MOSFET can be controlled from gate to source voltage signal. If the gate to source voltage of MOSFET exceeds threshold ... this configuration, the two switches (transistors) are used in totem pole arrangement with a comparator.

Description : Explain thyristor gate drive circuit.

Answer : Thyristor Gate Drive Circuit: The thyristor can be turned on by pulse voltage signal at gate terminal and it does not require continuous drive signal like the transistor. The gate ... circuit provide required minimum gate voltage and gate current then the thyristor conducts properly.

Description : basic gate drive circuit of GTO

Answer : basic gate drive circuit of GTO

Description : advantages and disadvantages of ICs.

Answer : Advantages of ICs: 1.The physical size of an IC is extremely small (generally thousand times smaller) than that of discrete circuits. 2. The weight of an IC is very less as compared to that of ... is high 3. Power dissipation is limited. 4. ICs are very delicate and need extra care while handling

Description : Enlist names of regulator IC’s .
