| Abstract |
The auxiliary resonant commutated pole inverter (ARCPI) is one of the most promising resonant inverter topologies
for high power drive applications. In this paper, a digital control circuit for the ARCPI is presented, which allows
compensation of the resonant time and thereby leads to a load-independent control characteristic of the inverter. For dimensioning of the resonant elements, a compromise must be found between the peak value and theRMS value of the resonant current and the switching time. In this paper, equations are given for these quantities as functions of the voltage' rise time of the main switches and the current rise time of the auxiliary switches. The main problem with the ARCPI is the realization of the auxiliary switches. In this paper, different auxiliary switch topologies are proposed and analysed. |
