Packaging of a power conversion circuit

A method comprising:

• configuring first circuitry including a first side of power conversion circuit and a first magnetic core on a first circuit board to form a first circuit assembly;
• configuring second circuitry including a second side of the power conversion circuit and a second magnetic core on a second circuit board to form a second circuit assembly;
• establishing a magnetic connection between the first circuitry of the first circuit assembly and the second circuitry of the second circuit assembly based on a predetermined distance between the first magnetic core and the second magnetic core;
• and
• establishing an electrical connection between the first circuitry of the first circuit assembly and the second circuitry of the second circuit assembly via at least one electrical connection,
• wherein the first circuit board and the second circuit board are of equal length.

A circuit assembly comprising:

• circuitry configured on an upper surface of a circuit board including a half of a power conversion circuit;
• and
• a magnetic core configured on the upper surface of the circuit board, wherein
• the circuitry is configured to connect to the circuitry of another circuit assembly to form the power conversion circuit via at least one of an electrical connection or a magnetic coupling between the magnetic core and another magnetic core of the another circuit assembly,
• wherein the circuit board and a circuit board of the other circuit assembly are of equal length.
