Abstract: An induction heating device comprises a D.C. power supply referenced to a ground connection. The D.C. power supply is configured to supply power to the induction heating device and comprises a voltage rectifier configured to rectify an input voltage into a direct current and output the D.C. voltage to a D.C. bus and a ground connection. The device further comprises a plurality of resonant loads arranged in a matrix comprising a plurality of columns and a plurality of rows. Each of the resonant loads is connected at a first end to a row and at a second end to a column. A plurality of first switching devices are in connection with each of the columns between the D.C. bus and at least one of the resonant loads. A plurality of second switching devices are in connection with each of the rows between the resonant loads and the ground connection.
