of the switch 268. It is used to detect whether the load 212 is an open-circuit wave rectifier 260, so that the full-wave rectification 55 switch 268 has a feed 踹, 蚣山Λϋ When the load 212 is open, a high-voltage pulse wave appears at both ends of the load 212, and the resonant circuit A large current also flows, so that the full-wave rectifier 26 can detect a large voltage at the ends of the control coil 234. When the sense voltage is greater than the preset voltage threshold of the start-up circuit 266, the start-up circuit 266 turns the switch 268' on to short-circuit the full-wave rectifier 260. When the full-wave rectifier 26 is short-circuited, the voltage across the fourth control coil 234 will drop to zero, while the voltage across the other coils also drops to zero 'so that the full-bridge converter stops the high-frequency switching action' to protect Electronic ballast. When the voltage across the control coil 234 drops to zero, the value of the detection voltage also decreases. When the value of the detection voltage is lower than the preset voltage threshold, the switch 268 is turned off, causing the electronic ballast 200 to return to normal. Work status 'This is the re-striking function. If load 212 is still open, the test will rise again and switch 268 is turned on to protect the circuit. It should be noted that, in this embodiment, only the full-wave rectifier 260 is electrically connected to the fourth control coil 234 to detect the voltage across the fourth selected coil 234, but the full-wave rectifier 260 is not limited.

Resistor 262c is connected in parallel with capacitor 262b to form a discharge circuit, and resistor 262a is a series discharge circuit to charge capacitor 262b. The first time adjustment circuit 262 can control the time during which the voltage is transmitted to the enable circuit 266. Therefore, the duration of the high voltage pulse across the load 212 can be controlled by adjusting the circuit parameters of the first time adjustment circuit 262. The electronic stabilizer 200 can be prevented from being damaged by appropriately adjusting the duration of the high voltage pulse. The time adjustment circuit 264 is electrically connected between the startup circuit 266 and the fifth switch 268 for controlling the time when the detection voltage is applied to the fifth switch 268.

When the value of the detection voltage is greater than the preset voltage threshold of the startup circuit 266, the startup circuit 266 turns on the fifth switch 268 and shorts the fourth control coil 234', that is, the voltage across the fourth control coil 234 is zero. .

The balancing capacitor 299 is electrically connected between the control coil 226 and the full-wave rectifier 26A to balance the currents flowing into the full-wave rectifier 260 to balance the switches 22〇, 228, 226, and 232. Work duty cycle (duty). Although the present embodiment only shows that the balancing capacitor 299 is electrically connected between the second end of the control coil 226 and the full-wave rectifier 260, it is not limited thereto. The balancing capacitor 299 can also be electrically connected between the second end of the control coil 234 and the full-wave rectifier 26A, so that the same effect can be obtained. Please refer to FIG. 16, which is a circuit diagram of a self-excited electronic ballast 1500 according to a fourteenth embodiment of the present invention. The self-excited electric handstand stabilizer 1500 is similar to the self-excited electronic ballast 7〇〇, but the difference is that the electronic ballast measurement includes a full-wave rectifier. The full-wave rectifier is electrically connected to both ends of the control coil 226. When the switch 268 is turned on, the 19 1375489 full-wave rectifier 360 shorts the control coil 226. Since the self-excited electronic ballast 1500 operates in a manner similar to that of the self-excited electronic ballast 700, it will not be described here. In addition, it is worth mentioning that the full-wave rectifier can also be applied to the electronic ampoule proposed by other embodiments of the present invention. While the present invention has been described above by way of a preferred embodiment, it is not intended to limit the invention, and the present invention may be modified and modified without departing from the spirit and scope of the invention. The scope of protection is subject to the definition of the scope of the patent application.
