A resonant power converter comprising electrical safety components (29b) comprising a combination of a diodes (Dn2) and a zener diodes (Zn) coupled between DC conductors and an auxiliary switching circuit, the diodes being adapted to hinder the current from flowing from the auxiliary switching circuit to the negative DC conductor, and the zener diodes being adapted to allow current to flow from the negative DC conductor to the auxiliary switching circuit when the potential difference between the negative DC conductor and the phase conductor is above a threshold voltage. The Zener diodes being selected such that the threshold voltage of the Zener diodes is below the maximum blocking voltage of the transistors. |
