| Abstract |
There has been a proliferation in recent years of inverter topologies which feature low switching loss, thus permitting high switching frequencies. Typical examples include resonant dc link inverters, resonant pole inverters, auxiliary resonant commutated pole inverters and many variations thereof. This paper presents a comparison of the various topologies based on important factors such as cost, component stresses, and spectral performance. Comparisons to conventional hard switching pwm inverters are also made. Limitations of individual circuits, in particular, the ability to realize goals of high switching frequency and low loss are also addressed in detail. |
