摘要:An integrated circuit controls a power converter that includes single stagebuck-boost converter and a switching full bridge that may be used to drive an HID lamp.The single stage buck-boost converter reduces the complexity and parts count of the
power converter, or electronic ballast, while permitting PFC and DC bus voltage
regulation under control of the integrated circuit. The integrated circuit also provides allthe drive signals to operate the switching full bridge circuit to maintain constant poweron the HID lamp. A wait timer provides an interval of time between restart attempts forthe HID lamp to permit the lamp to cool so that high hot restart voltages are avoided.The integrated circuit simplifies the design of power converters and electronic ballasts inparticular, while contributing to reducing part count, complexity and cost in conjunctionwith the single stage buck-boost converter.
