Power Loss in MOSFET Solution

STEP 0: Pre-Calculation Summary

Formula Used

Average Power Loss = Drain Current^2*Drain Source Resistance
P_loss = I_d^2*R_ds
This formula uses 3 Variables

Variables Used

Average Power Loss - (Measured in Watt) - Average power loss is the power loss when transistor device is in working state.
Drain Current - (Measured in Ampere) - Drain Current is the current that flow through the drain junction of the MOSFET and IGBT.
Drain Source Resistance - (Measured in Ohm) - Drain source resistance in MOSFET is defined as the opposition faced by the current flowing through the drain source terminals.

STEP 1: Convert Input(s) to Base Unit

Drain Current: 105 Milliampere --> 0.105 Ampere (Check conversion here)
Drain Source Resistance: 17 Kilohm --> 17000 Ohm (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_loss = I_d^2*R_ds --> 0.105^2*17000

Evaluating ... ...
