Besides the deployment of Power Bridge, a group of large capacitors that meet the requirements of today’s high performance
motherboard design. The theory behind this is long transmission lines have considerable inductance and capacitance as well as
resistance. When a current flows through the line, inductance and capacitance have the effect of varying the voltage on the line
as the current varies. Thus the supply voltage varies with
the load. Several kinds of devices are used to overcome
this undesirable variation, in an operation called regulation
of the voltage. They include induction regulators and
three-phase synchronous motors (called synchronous
condensers), both of which vary the effective amount of
inductance and capacitance in the transmission circuit.
Inductance and capacitance react with a tendency to
nullify one another. When a load circuit has more inductive
than capacitive reactance, as almost invariably occurs in
large power systems, the amount of power delivered for a
given voltage and current is less than when the two are
equal. The ratio of these two amounts of power is called
the power factor. Because transmission-line losses are
proportional to current, capacitance is added to the circuit
when possible, thus bringing the power factor as nearly as
possible to 1. For this reason, large capacitors are
frequently inserted as a part of power-transmission
systems.
