Open-circuit fault diagnosis of traction inverter based on compressed sensing theory

Open-circuit fault diagnosis of traction inverter based on compressed sensing theory

This study proposes a new method of fault diagnosis based on the least squares support vector machine with gradient information (G-LS-SVM) to solve the insulated-gate bipolar transistor(IGBT) open-circuit failure problem of the traction inverter in a catenary power supply system. First, a simulation...
