Abstract
A balanced switching amplifier for a magnetic bearing assembly may include a first switching amplifier configured to drive a first load of an electromagnet of the magnetic bearing assembly via a first plurality of lead wires. The balanced switching amplifier may also include a second switching amplifier configured to drive a second load of the electromagnet via a second plurality of lead wires. The first switching amplifier and the second switching amplifier may be configured to operate in tandem such that respective voltages in the first plurality of lead wires and the second plurality of lead wires substantially neutralize one another, thereby reducing electromagnetic emissions from each of the first plurality of lead wires and the second plurality of lead wires.
