Document Type and Number:
Japanese Patent JP2013529828
Kind Code:
A
Abstract:
An electronic high intensity discharge (HID) ballast (102) is presented which includes a dual mode buck converter (120) providing a DC output voltage (122) to drive an inverter (140), where the buck converter (120) regulates the DC output voltage (122) to a first value in normal operation and a clamp circuit (134) changes the converter mode to clamp the DC output open circuit voltage when the converter DC output exceeds a reference value (Vref).
