N2 - This paper presents a single-stage soft-switching high-frequency link isolated converter for bidirectional motor drive applications. The 'minimal' topology is based on the recently proposed soft-switching solid-state transformer (S4T) with a single current-source power conversion stage. This single stage approach reduces total switch rating, provides sinusoidal input and output voltages, and uses zero-voltage switching (ZVS) to reduce switching losses, dv/dt, common-mode noise issues associated with conventional PWM converter drives. Moreover, a high-frequency transformer is employed for dramatic size and cost reduction compared with drives that use standard line frequency transformers for isolation - a very common practice. The modulation scheme ensuring ZVS for entire load and power factor operating range considering the effect of leakage inductance of the high frequency transformer is presented in this paper. The effectiveness of the presented four-quadrant motor drive converter is verified by both simulation and experimental results.
