一种无需在每个开关管两端并联独立谐振电容的高效谐振直流环节逆变器

Many existing resonant dc-link inverters incorporate separate shunt resonant capacitors for at least one switch. However, when the voltage across these capacitors exceeds zero, the accidental switching-on of the switches due to control disturbances in industrial applications can trigger a sudden discharge of the capacitors, resulting in electrical surges, increased switching-on losses, and potenti...
