If the supply voltage is +/.18V and the switching frequency is 40kHz, then this corresponds to roughly 1 W of dissipated power. However, as mentioned, this is a pessimistic approach, as it assumes that the Y-capacitors get charged and discharged with the full filter supply voltage. ... The measurements presented in the previous sections were all performed running the active filter from 9V batteries, ...
