The single-stage indirect matrix converter (SSIMC) has emerged as a promising solution for DC fast chargers (DCFC) and front-end rectifiers, offering galvanic isolation, high power density, and improved efficiency compared with conventional two-stage converters. However, existing SSIMC modulation techniques are predominantly based on numerical or space-vector methods, optimized primarily for unity power factor operation. These approaches require complex current controllers at both the primary matrix converter and the secondary full-bridge stage to achieve reactive power control, which increases implementation complexity. To address this limitation, this paper introduces a translation-based modulation strategy that enables the direct application of well-established voltage-source inverter (VSI) decoupled power control theory to the SSIMC topology. The proposed approach significantly simplifies control implementation while maintaining full reactive power capability. Experimental validation using a low-power SSIMC prototype demonstrates the effectiveness of the proposed method.
