The ZVS Buck-Boost regulator array provided the tight regulation required by the equipment. This was replicated for the redundant system. The Customer's Challenge Used to direct railway traffic and keep trains clear of each other at all times, reliability is a fundamental requirement for rail signaling equip- ment; the travelling public expect it and governments regulate for it. One company was upgrading the functionality of its rail signaling equipment to improve performance and reduce whole life costs and operational risks, with a resultant increase in power required. To meet enhanced reliability targets a fully redundant
