Losses in PWM inverters using IGBTs

摘要

The authors comment on the paper by F. Casanellas titled 'Losses in PWM inverters using IGBTs' (see ibid., vol.141, p.235-9, 1994). They suggest that Casanellas only gives a relatively coarse estimate concerning the reduction of the switching losses of discontinuous modulation in comparison to continuous modulation and expand on this subject. The original author replies to the comments.
