In a first aspect, a switched-mode power supply circuit topology electrical power can be transferred between a source and a load across an antisymmetric transformer having a primary coil and a secondary coil. First and second switches are provided for respectively switchably coupling the primary coil across the source and the secondary coil, the switches being bi-directional. A controller controls the switches so that they can act synchronously with a predetermined mark-to-space ratio, which determines the voltage ratio between, the circuit topology comprises an inductor and is for transferring power between a source and a load, a common rail coupling one voltage terminal of the source and one voltage terminal of the load. Bi-directional switches are controlled to couple the ends of the inductor to the voltage terminals of the source and the load to control the power transfer.
