As the MOSFET is a voltage controlled device, so for turning ON the MOSFET, the Gate to Source Voltage (Vgs) must be greater than the Gate to Source Threshold Voltage (Vth).. In this method, the voltage is applied at drain and gate of MOSFET by separate power supplies.. In this configuration, When a trigger voltage is applied to the gate then MOSFET has a very low drain to source resistance i.

In high side configuration, the load is connected between the source of the MOSFET and the ground.. These concepts will crystal clear the working of MOSFET as a switch and will so justify the use of MOSFET in the inverter circuit as switching component.. This resistance also discharge the parasitic capacitance of the MOSFET Otherwise, the MOSFET can get damaged as this parasitic capacitor will keep on charging and exceed the limit of the gate to source breakdown voltage.. Also, do not exceed the input voltage (drain voltage and gate voltage) of MOSFET greater than its breakdown voltage as it can damage the MOSFET.. Ir2110 Mosfet Circuit Diagram Driver IC WhichThat means when MOSFETIGBT is used in High side configuration then a gate driver IC is needed.. A Gate Driver is a specially designed circuit that is used to drive the Gate of MOSFET or IGBT in High Side Switching application.. But the input voltage is only 5V, that means the high side MOSFET cannot be driven by applying the same voltage at the base and drain of MOSFET.. A low-value resistor (10E to 500E) should be used at the gate of MOSFET This will solve the problem of ringing (parasitic oscillations) and voltage spike in the MOSFET.. The load (shown as resistance RL in the circuit diagram) is placed in between the drain and the power supply.. Since MOSFET is a voltage controlled device, for providing appropriate voltage drop at the terminals of the MOSFET, some resistors need to be connected at the gate and source of the MOSFET. b0d43de27c
