WHEN designing power converters it is always a goal to
reduce the price and the physical size, i.e. increase the
power density. The development of switch mode power supplies
(SMPS) has made it possible to increase the power density
significantly, but it is limited by the size of the passive energy
storing components (inductors and capacitors). The value and
size of these are however dependent on the switching frequency.
By increasing the switching frequency it will hence be possible
to reduce the size of SMPSs further
