ABSTRACT:
A regulated switched-mode power supply for a television receiver utilizes a high voltage power transformer. A transformer primary winding, energized in response to a pulse width modulated signal, energizes electrically isolated load circuit windings via transformer action to transfer energy from an unregulated voltage source. A supplemental transformer winding, magnetically coupled to the primary winding, transfers additional energy to the load circuits to maintain accurate load circuit voltage regulation under all receiver operating conditions.
