1. A resonant DC-DC power converter comprising:

  • a single substantially flat carrier substrate comprising a first surface and a second, opposing, surface,an input side circuit comprising a positive and a negative input terminal for receipt of an input voltage or current,an output side circuit comprising positive and negative output terminals for supply of a converter output power, voltage or current and connection to a converter load,a rectification circuit connected between an output of a resonant network and the output side circuit,wherein the resonant network is configured for alternatingly being charged from the input voltage or current and discharged through the rectification circuit by a first controllable switch arrangement in accordance with a first switch control signal, wherein a frequency of the switch control signal is at or above 20 MHz,a second controllable switch arrangement configured to select a first impedance characteristic of the resonant network in a first switch state and select a second impedance characteristic of the resonant network in a second switch state, andan output voltage or current control circuit configured to adjust the converter output voltage and/or current by activating and interrupting the first switch control signal in accordance with a switch state of the second controllable switch arrangement,wherein the input side circuit, the output side circuit, the rectification circuit, the resonant network, the first controllable switch arrangement, the second controllable switch arrangement and the output voltage or current control circuit are attached on the first surface and/or second surface of the single substantially flat carrier substrate.
