DC-AC Converters (inverters) • The function is to convert a DC fixed voltage into a symmetric AC output of fixed or variable frequency and amplitude • Applications: • variable speed AC drives • Uninterruptable AC power supplies • Single phase and 3 phase applications.
Principle of operation (half-bridge inverter) Output voltage is v0=vA-vO
The state of switches 6 1 2 3 4 5 | 6 1 2 3 4 etc.
