Patent GB-2084816-A (GB)
Title: DC-DC converter
IPC: H02M3/337
Filed: 1981-09-03
Abstract: In a DC-DC converter working on the current resonance principle, the input DC is applied to a resonant circuit including a capacitor (C1) and the primary of a transformer (RT) via four transistors (T1, T2, T3, T4) connected as a bridge. The transformer's secondary feeds the output (A1-A2) via a Graetz rectifier (G) and smoothing components (C2-L-C3). The resonant circuit (C1-RT) is in series with a limiting resistor (W1) to reduce current consumption when switching on and off. One leg of the output includes a relay (R) acting as a DC sensor, and when the output DC reaches a preset threshold the relay operates and its contact (r) switches two more transistors (T5-T6) to short circuit the limiting resistor (W1). On switch off, the relay (R) releases at another - and lower - threshold to remove the short circuit for the limiting resistor. Developed for use as a DC supply for a travelling wave tube. <IMAGE>
