Abstract
A signal is coupled from the primary to the secondary of a transformer, to a signal receiver which has a supply voltage derived from the signal via a rectifier arrangement including a filter capacitor. A plurality of signal drivers on the primary side have their outputs enabled by output enable signals with different timing for different ones of the drivers. The different timing includes small delays to spread crowbar currents over a short period, enabling an increasing number of drivers with increasing initial charge of the capacitor, and disabling drivers while others remain enabled, in order to reduce peak currents and kick-back voltages.
