In the previous paper, published last month
[1], the general aspects of Power Electronics
and the high power range applications were
reviewed. The many existing applications
throughout industry, transport, public buildings,
communications, computing, home automation
and electro-medical devices, mainly in the role
of feeding power to equipment and systems,
were presented. As shown, the power range is
very wide, covering from over fi ve thousand
megawatts in High Voltage DC Transmission to a
few tenths of a watt in micro-power converters
for mobile telephones and electro-medical
devices. In this second and last paper the
medium and low power range applications,
normally with important weight and size
restrictions, are reviewed.
