We knows Two Types of Inverter Circuits
1.Traditional Inverters Buck/Royer
2.Direct Drive (Simplified Advance)
1. The traditional Buck/Royer inverter topology is essentially a combination of a step-down
Buck Voltage regulator and a self-resonant Royer oscillator with an integral step-up transformer. From one decade, display makers employed a Buck/Royer inverter topology to strike and power CCFLs. This analog power topology is essentially a combination of a step-down Buck voltage regulator and a self-resonant Royer oscillator with an integral step-up transformer.
2. A simple inverter topology that could optimize performance, reduce component count, and lower costs implements a Direct Drive architecture that eliminates the inductor and resonant capacitors found in a conventional Royer oscillator.
CCFLs, Inverter ideally takes DC-12 volts from power supply board in LCD Monitor / TV and
In Laptop from NIMH Battery. The circuit operation and functions of LCD inverter same like
Un-Interrupted Power supply (UPS) characteristics.
In addition, LCD Inverter takes DC-12 Volts from supply and starting signal pulse from main board, which fire the overall process in the inverter circuit. Switching is present, so as to start the controlled oscillation through inverter dimming controller IC chip. Which controls several functions.
For example, Short circuit protection, Temperature control, Power, Humidity and Dimming in order to error free high and low CCFLs lighting. The most essential and compulsory section of an inverter is high voltage transformer. Which produces up to 600- 800 Voltages output to match ambient light conditions and requirements. It provides an alternating current source to drive the lamp. Lamp current will be the total transformer Output voltage minus the lamp voltage (lamp voltage is inversely proportional to current) divided by
the capacitor's impedance.
