Abstract
The invention relates to a high-frequency driving device for an electrodeless lamp, including a PCB (Printed Circuit Board), a first power supply, a second power supply, a crystal oscillator unit, and a driving chip, wherein the crystal oscillator unit and the driving chip are connected to the PCB, the first power supply supplies power for the crystal oscillator, the second power supply supplies power for the driving chip, and is connected to a power supply of a controller main board through a connector. When a nominal voltage reaches the crystal oscillator, the crystal oscillator unit outputs a standard pulse square wave with the frequency of 2.65M. The square wave reaches the driving chip. The driving chip outputs two groups of driving signals and drives an MOS tube to work through elements on the controller main board. The above technical scheme achieves the reduction of the element number, and smaller signal attenuation, and higher driving signal stability, so that the power consumed by the driving chip of the driving device is greatly reduced, thus the driving device can safely, efficiently, and stably work without fault in various environment temperatures. Moreover the technical scheme also has technical effects of convenient installation, standard production and manufacture technologies, and simple structure.

Background technology
At present, existing electrodeless lamp high frequency drive circuit is generally formed oscillator by electric capacity, resistance, transistor, and the pulse of oscillator output is used for the driven MOS pipe.But serious frequency drift phenomenon can appear in the electrodeless lamp controller that uses above-mentioned discrete components and parts to make, and the drive signal amplitude size is indefinite, makes MOS can't be in optimum Working.In actual applications, manufacturing and the debugging work of controller that has above-mentioned drive unit is all very difficult, the failure rate height of controller, and the technical indicator that can reach is also lower.
Summary of the invention
For solving the electrodeless lamp controller frequency drift that exists in the prior art and the problem of drive unit jitter, the invention provides a kind of high stability, drive output constant and can make that electrodeless lamp controller failure rate declines to a great extent, the equal electrodeless lamp high-frequency drive device comparatively easily of technology compactness, installation and manufacturing.
To achieve the above object of the invention, the technical solution adopted in the present invention is:
A kind of electrodeless lamp high-frequency drive device, it is characterized in that: it comprises that pcb board, first power supply, second source, 2.65M crystal oscillator unit, IXDF404SI drive chip, 2.65M crystal oscillator unit and IXDF404SI drive chip and insert pcb board, first power supply is the power supply of 2.65M crystal oscillator unit, second source is that IXDF404SI drives chip power supply, and second source is connected with the power supply of controller mainboard by a connector.
Technique scheme can also be further perfect:
As preferably, 2.65M crystal oscillator unit is a 2.65M main oscillations pulse generator, and IXDF404SI drives chip and is connected with the controller mainboard by a plug-in pin.
As preferably, when nominal voltage arrives 2.65M crystal oscillator unit, crystal oscillating circuit output 2.65M calibration pulse square wave drives chip to IXDF404SI, and IXDF404SI drives chip and exports two groups of driving signals, and two groups drive signals is to drive signal to the metal-oxide-semiconductor that the controller mainboard provides.
In the technique scheme, crystal oscillator unit, driving chip are connected with pcb board, export one road voltage respectively to the circuit supply on the pcb board by first power supply and second source, second source is both for driving chip power supply, be connected with the controller mainboard by a connector again, make drive unit be communicated with motherboard power supply.When nominal voltage arrived crystal oscillator, the calibration pulse square wave of a 2.65M of crystal oscillator unit output, this square wave arrived and drive chip, and the driving chip is exported two groups and driven signal, does by the components and parts driven MOS plumber on the controller mainboard.Technique scheme has realized the minimizing of the quantity of components and parts, and has less signal attenuation, higher driving signal stabilization degree, drive unit drive the power that chip dissipates and significantly reduce, thereby can reach safety, efficient, stable, unfailing service in various ambient temperatures.In addition, that the technical program also has is easy for installation, production and manufacturing process standard, technique effect simple in structure.
