TLDR
In this article, a TV/radio converter using the common power supply having remocon circuit including main power taking-out device in which applied AC power makes main power be applied to the next stage through switching-mode power components and dc-converting components, the device includes; a constant voltage device coupled in the output stage of the switchingmode power component and DC converting component.Abstract:
A TV/radio converter using the common power supply having remocon circuit including main power taking-out device in which applied AC power make main power be applied to the next stage through switching-mode power components and dc-converting components, the device includes; a constant voltage device coupled in the output stage of the switching-mode power components and DC-converting components, wherein the output of the switching mode power components drives the microcomputer (MICOM) and can apply the constant voltage to the next stage, a main power control device, wherein the output of the MICOM controls the input power of horizontal driver components through active components in company with the output of the constant voltage device, thereby controlling the driving power of the TV and radio, and a driving device of a radio, wherein the radio operation can be carried out by driving the switching components using the output of the main power control device and the static voltage device after the active components are driven by the output of the main power control stage. Grading the product up to high-qualified level may be attained.read more
