Current source inverters (CSIs) feature additional attention, compared to voltage source inverters (VSIs), because of their advantages, like inherent current short-circuit proof and low output voltage THD. The major constrain for CSIs is the necessity of the DC-link current continuity. Transient over-voltage occurs in case of DC-link current interruption due to failure of IGBT/series diode/gate driver. The non-robust behaviour of IGBT at breakdown voltage makes fast over-voltage protection adoi:10.1049/cp.2011.0159 fatcat:gkxzm54euzebng4igliifq73zy
