Power Converter Circuits reveals all key components of rectification, inversion, cycloconversion, and conversion circuits. It describes switching, voltage, and current relationships, as well as converter properties, operation, control, and performance as utilized in most practical applications. Authored jointly by a veteran scholar and an accomplished researcher in the field, the book highlights methods grounded in classical mathematics and includes an abundance of worked numerical examples. It authoritatively covers AC to DC, DC to AC, AC to AC, and DC to DC converters in a single volume and features hundreds of chapter-specific problems, with solutions provided separately at the end of the book.

During the Peloponnesian War the Athenians occupied the promontory of Pylos to counter Sparta's repeated invasions of Attica. Over two days of fighting the small garrison beat off the Spartan army and the returning Athenian fleet won a victory in the nearby waters, stranding a contingent of elite Spartan hoplites on the island of Sphacteria.

In 480 BC, the Greek and Persian fleets met in a battle in the strait between Attica and the island of Salamis. Although outnumbered, the Greeks delivered a victory that ended the Persian threat to Greece. This book draws on the findings of archaeological, technological and naval research to recreate an important naval campaigns in world history.
