what is reactive and active power?why we need power factor correction?
Answer Posted / cracked
reactive power - power drawn from the supply for the
excitation (production of magnetic field) of magnetic
coils/circuits of the machine.
so when using machine with large windings, consumption of
reactive power is more which leads to poor power factor and
hence power factor correction is needed.

Is there a possibility to use such a treshold voltage for the NMOS part of a CMOS circuit that during the switching it will start conducting only after the PMOS part will be already closed, by this eliminating the leakedge current? Please note, I'm not asking about the well bias in standby mode, but about the "antileakedge" measures during normal operation.
