摘要： The present invention relates to a bi-directional DC-DC resonant converter (1) with bi-directional voltage control. A resonant tank device (RTD) has first and second primary resonant tank terminals (a1, a2) defining a primary resonant tank voltage (Ua) and first and second secondary resonant tank terminals (b1, b2) defining a secondary resonant tank voltage (Ub). The resonant tank device (RTD) comprises a configuration switch (RS) for configuration of the converter (1) between a first state, in which power is transferred from the secondary converter terminals (TCb1, TCb2) to the primary converter terminals (TCa1, TCa2), and a second state, in which power is transferred from the primary converter terminals (TCa1, TCa2) to the secondary converter terminals (TCb1, TCb2). A first gain Gres1 when operating at a first series resonance frequency (ω res1 ) in the first state is different from a second gain (Gres2) when operating at a second series resonance frequency (ω res2 ) in the second state.
