This paper proposes a method for fault diagnosis and fault-tolerant control of DC-link voltage sensor for two-stage three-phase

grid-connected PV inverters. Generally, the front-end DC-DC boost converter tracks the maximum power point (MPP) of PV array

and the rear-end DC-AC inverter is used to generate a sinusoidal output current and keep the DC-link voltage constant. In this

system, a sensor is essential for power conversion. A sensor fault is detected when there is an error between the sensed and

estimated values, which are obtained from a DC-link voltage sensorless algorithm. Faulttolerant control is achieved by using the

estimated values. A deadbeat current controller is used to meet the dynamic characteristic of the proposed algorithm. The

proposed algorithm is validated by simulation and experiment results.
