Abstract

Resonant link techniques allow high operating frequencies to be attained by providing instances of zero voltage or current at which the main power devices may change state. By replacing the d.c link of conventional hard switched inverters with a high frequency oscillatory link, the switching losses are reduced and the devices may operate at higher frequencies. A result of the resonant link technique is that the switching instants are fixed by the zero crossings of the link oscillation and the output waveform must be made up of integral pulses of the link waveform. This lead to an output spectrum that is significantly different from hard switched inverters where PWM techniques may be used.
