Abstract
In a television receiver having an SCR switching regulator power supply, excessive power supply loading or high line voltage may cause abnormal operation of the switching SCR resulting in a rapid variation of the regulated supply voltage above its regulated level. This voltage variation causes high peak current in the horizontal output transistor, causing it to fail. A detector circuit monitors both the average current and the peak current through the horizontal output transistor and causes the receiver to be disabled in the event either current level becomes excessive.
