An FET full-bridge switcher for inductorless capacitor charging for Nova
Abstract
Switching power supplies which were designed and exceeded the requirements of the Nova 10 mm rod amplifiers are examined. A full bridge with fast recovery diodes is used to improve FET turn off and improve efficiency. The leakage reactance of the transformer effectively limits current so that an inductor is not required. The pulse width is programmable, making them variable frequency power supplies, and may be controlled by a computer or other device for special loads. Higher power can be attained by using heftier transformers and transistors and going to a 480 Vac, Vdc bridge.
