There are multiple fault causes coupling in DC side of photovoltaic inverter. The changes of voltage, current and power are derived by fault mechanism analysis. The differences of failure feature are used to locate the fault cause.
In electric vehicle (EV) charging and solar inverter systems, current sensors measure current flow by monitoring the voltage drop across a shunt resistor or the magnetic fields generated by current flowing through a conductor. These high-voltage systems use current flow information to control and monitor power conversion, charging and discharging.
Due to the different mechanisms of DC faults caused by different causes, there are obvious differences in characteristic such as voltage and current. Using the fault features of grid-connected inverters, a fault diagnosis process combining multiple technical means is proposed.
A traction inverter controls the electric motor and is a key component in the HEV/EV drivetrain. A traction inverter requires accurate current sensing at high common-mode voltages. Current measurements in traction inverters can therefore be realized using one of two shunt-based methods.
In order to limit output level of inverter, there is often a limiter in control circuit. The inverter output dq axis voltage ud and uq after passing through current inner loop are used as the input of sinusoidal vector pulse width modulation (SVPWM), and then realizes the conversion from DC to AC.

2.2. DC overvoltage fault The condition of DC overvoltage fault in inverter is that the DC capacitor voltage exceeds maximum allowable voltage Umax and maintains for a period of time, which triggers overvoltage protection and causes the inverter to stop.
