Abstract

The usage of an Auxiliary Resonant Commutated Pole (ARCP) circuit with an 11-level Cascaded H-Bridge (CHB) converter as an option for feeding high-power Wireless Power Transfer (WPT) track-pads in traction applications is proposed in this research. By utilizing a mathematical model to obtain the switching pulses of the ARCP circuit, a reduction in the conduction losses of the involved inductance can be achieved. Moreover, an optimization routine is developed to reduce the MOSFETs' root mean square current by finding each module's phase shift angles. The study uses the SAE J2954 standard to restrict the Electromagnetic Interference (EMI) in the frequency band between $400\ kHz$ and $30\ MHz$. The success of the suggested technique is displayed by simulation results showing that it is possible to operate the CHB with Zero Voltage Switching in all modules of the power converter. Inductive Power Transfer applications applied in railways can benefit from this contribution due to the use of multilevel converters.
