Abstract :
A 150kVA three-phase triport uninterruptible power system(triport UPS) employing transistor inverters has been developed. By using a core type for the triport transformer, we get higher efficiency and a reduction in temperature of transformer and its weight. A three-phase control circuit becomes simpler and more reliable by using a saturable core and an integrator.
