Working Principle:

Upon activation of the high-frequency shaking circuit loop, the PTC thermistor starts at a normal temperature where its resistance is significantly lower than that of component C2. This facilitates minimal initial light pressure, allowing the current through C1 and Rt to establish a preheating circuit for the filament. As the PTC resistor heats up beyond the Curie temperature, Rt’s temperature surpasses the critical switch temperature (TSW). Within 0.4 to 2 seconds, Rt shifts to a high-resistance state, greatly exceeding C2’s resistance. This change enables the current through C1 and C2 to create LC resonance, thus generating the high voltage necessary for lighting the fluorescent tube.
