A method of controlling the primary or secondary side converter of a wireless power transfer (WPT) or an inductive power transfer (IPT) system includes optimising a load impedance, and controlling one or more of a duty cycle or relative phase angle to reduce or minimize the converter losses at the optimal load impedance

    L'invention concerne un procédé de commande du convertisseur côté primaire ou secondaire d'un système de transfert de puissance sans fil (WPT) ou de transfert de puissance inductive (IPT), ledit procédé comprenant les étapes consistant à optimiser une impédance de charge et à commander un cycle de service et/ou angle de phase relatif, pour réduire ou minimiser les pertes de convertisseur à l'impédance de charge optimale.
