    How to do power measurement in LT SpiceXVII

    Please help me to find total,dynamic,leakage power dissipations in a simple inverter circuit using LT Spice XVII

    measure the voltage and current on input and output
    use the "add a trace" function in graphical output display to find V * I on input and output

    power in should be > power out
    and this should give you (at least a start) at total power.

    not quite sure what you are looking for in leakage power

    Review the waveform arithmetic chapter in the Ltspice online help.

    Voltage, current and power quantities of switched mode circuits are mostly pulsating. It's helpful to use average display feature, preferably applied to one switching period.
