We report on a study of 3 post common-envelope binary systems; EC 11575-1845, V644 Cas (the central star of the PN HFG 1), and VW Pyx (the central star of K 1–2). These 3 have similar photometric and spectroscopic characteristics. Emission lines from the heated face of the cool star move with different velocities, and the H I lines are very broad with deep absorption component(s) visible at all phases.
