A linear generator, which utilizes harmonic magnetic field by ground coils has been developed for on-board power source for the Electro Dynamic Suspension (EDS) Maglev. The linear generator is composed of generator coils and a PWM converter which can compensate reactive power and control output power by detecting instantaneous current and generating equivalent voltage in a RC circuit. However, in the case of controlling any phase to generate magnetic damping, interference between output and phase occurs and the output fluctuates.This paper examines the output and phase control in the converter of linear generator and proposes the improved method to reduce the interference between output and phase control. By using numerical examples, we reveal the performance of the improved control system, and verify their performance in the bench test.
