WebCalculation of Power Loss (Synchronous Rectification Type) Gate Charge Loss Gate charge loss is a power loss ascribed to MOSFET gate charging. It depends on the gate electric charge (or the gate capacity) of the high-side MOSFET and low-side MOSFET. Gate charge loss is calculated using the following formula. 2 À L k 3 Ú ? Á E 3 Ú ?

WebFeb 2, 2014 · First let’s rename the term power dissipation to power loss. This might start to make sense. Power loss is caused by the transistor’s (or any other part) internal resistance and flowing current ( P = R * I2) and it makes the transistor hot. If the N-MOSFET gate is grounded (or below the ground) then the internal resistance is extremely high ...

Each line represents power dissipation allowed in the MOSFET for a specific pulse width t P, with tP ranging from microseconds to infinity (DC). For instance, the graph shows that for a 10ms pulse the MOSFET can have 5V across drain-to-source with 50A flowing through it, which calculates to 250W of power dissipation.
