This two level PWM resonant DC link circuit capable of adjusting DC line bus voltage-clamped PWM and zero voltage holding PWM period in DC bus line can realize the soft-switched chopper operation under the principle of soft-switching. Its operating circuit analysis in repetitive steady-state is performed. This type of soft-switching inverter using two level PWM resonant DC link which includes an optimum type digital voltage servo controller in the d-q coordinate frame is presented and its new pulse pattern sinewave space vector modulation is demonstrated in order to minimize the switching losses and conduction losses. It is proved that this inverter topology is more effective to reduce the switching losses as well as the conduction losses of the active power switches (IGBTs) with three-phase bridge arms and resonant DC link snubber.","PeriodicalId":215980,"journal":{"name":"21st International Telecommunications Energy Conference.

Technology allows us to transform a raw energy source, such as coal, into a more usable form, such as electricity, which has underpinned the impressive growth in living standards in the industrialised world. But at the same time, man has become increasingly aware of the limits of his unchecked use of some energy sources. The threat of global warming may change long-term energy prospects entirely. A third of the earth's 6 billion inhabitants still live without electricity. In their quest for growth, they will want to utilise their share of the Earth's energy resources. A new course will have to be taken. It already has a name-\"sustainable development\", which implies that progress must \"meet the needs of the present without compromising the ability of future generations to meet their own needs\" (Changing Course, 1992). But development relies on energy. And energy needs technology to make it available in an acceptable, sustainable way. The authors discuss energy technologies and the Kyoto protocol with particular reference to CO/sub 2/ reduction. ABB's commitment to sustainable development and activities in this area are also discussed.","PeriodicalId":215980,"journal":{"name":"21st International Telecommunications Energy Conference.
