Quasi-resonant pole inverter |
摘要 |
A quasi-resonant pole inverter provides soft-switching of the main inverter switch devices only when such opportunities are required by the pulse width modulation control. The inverter includes a main switching section and an auxiliary switching section. A phase-pole of the main switching section swings from source to ground potential with the assistance of the auxiliary switching section. The phase-pole swings from ground to source potential with the assistance of the auxiliary switching section. Low switch stresses are characteristic in both the main switching section devices and the auxiliary section switching devices. Main power is carried predominantly through the DC rails thereby minimizing power handling requirements of quasi-resonant reactive components.
