| Abstract |
In this paper, a passively clamped quasi-resonant DC link converter is analysed, implemented and
evaluated in a battery charger application. Design expressions for selection of passive component
values, based mainly on the specified maximum output voltage derivative and the duration of the zero
voltage interval, are given. Design of the inductive components and selection of appropriate power
semiconductors for the quasi-resonant DC link are investigated. The main problems regarding power
electronic design of these components are also discussed. The quasi-resonant DC link waveforms are
measured and the converter efficiency is measured and compared to a hard switched case. |
