Abstract

This paper presents the challenges of implementing in-situ prognostics to practical power converters and proposes a new on-state voltage (VDSON) monitoring circuit for the high-side power transistors. The proposed approach references the drain of the high-side transistors for their VDSON measurement. This circuit allows VDSON measurement of not only multiple high-side transistors but also multiple low-side transistors at the same time. The measured VDSON is used to calculate on-state resistance (RDSON) in real-time using the drain-current measured using an off-the-shelf hall effect current sensor. The proposed circuit is used in a 75 kW 1000 VDC three-phase DC-AC inverter for in-situ prognostics. Validations of the proposed VDSON measurement circuit and RDSON monitoring are presented using theoretical circuit analysis and experimental results. The measured RDSON is found to be in the datasheet specified range.
