Something else I see is this: for calculating power dissipation for R2 resistor we use .meas Prg1 avg V( *DRV1* ,G1)*I(R2), but for calculating the power dissipation for R3 resistor we use this .meas Prg2 avg V( *IDRV2* ,G2)*I(R3). So, in one case we use a voltage, and in the other case we use a current. Web.meas is a command in LTspice that is used to specify measurements to be made on waveforms. The syntax is: .meas [] The name is a label that will be used to identify the measurement. The nodes are the nodes that you want to measure the voltage between. The expression is an optional mathematical expression that will be applied to the …
