Abstract
This paper studies the performance of a modular class-D switching amplifier to supply the drive field coils of a magnetic particle imaging scanner with a high quality sinusoidal voltage. While a class-A or class-AB amplifier is capable of delivering such a sinusoidal voltage, its low efficiency does not qualify for an economic solution. Therefore, a class-D amplifier has been used. The modular amplifier consists of commercially available class-D amplifier chips, which are connected in parallel, to achieve the required output power. This paper describes the simulation model and a hardware setup of the modular amplifier which consists of 10 chips connected in parallel.
