The dielectric withstand characteristics of each converter is tested in production to ensure barrier integrity. During the development of the PWR13XX Series extensive testing was done to verify that subjecting the barrier to as many as ten barrier tests will not destroy the barrier. The PWR13XX Series uses advanced circuit design and packaging technology to realize superior reliability and performance. A 220kHz driven push-pull oscillator is used to ensure stable frequency and non-saturating operation of the input stage. This means there are no high peak voltages or currents like other design topologies, which
