Partial discharges (PDs) pose significant risks to insulation systems by degrading materials over time, potentially leading to system failures. This study evaluates three pulse width modulation strategies-SPWM, SVPWM, and DPWMin-to assess their impact on PD activity and insulation life. Utilizing a high-voltage setup (up to 4 kV) with a half-bridge inverter controlled by Arduino, the research compares these strategies under various conditions. Results demonstrate that the DPWMin strategy significantly outperforms its counterparts, reducing PD activity and extending insulation life. This superior performance is attributed to fewer voltage flanks, which reduces cumulative stress on insulation materials.

Abstract
Partial discharges (PDs) pose significant risks to insulation systems by degrading materials over time, potentially leading to system failures. This study evaluates three pulse width modulation strategies-SPWM, SVPWM, and DPWMin-to assess their impact on PD activity and insulation life. Utilizing a high-voltage setup (up to 4 kV) with a half-bridge inverter controlled by Arduino, the research compares these strategies under various conditions. Results demonstrate that the DPWMin strategy significantly outperforms its counterparts, reducing PD activity and extending insulation life. This superior performance is attributed to fewer voltage flanks, which reduces cumulative stress on insulation materials.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
