Description
Technical field
The present invention relates to a kind of drive circuit, exactly is a kind of driving circuit of HF lamp without electrodes.
Technical background
HF lamp without electrodes is a kind of high light efficiency, and the long-life, the new light sources of environmental protection and energy saving has positive meaning for energy-saving and emission-reduction.The development of Non-polarized lamp comes into one's own in various countries.Drive circuit is the important component part of HF lamp without electrodes.The HF lamp without electrodes high frequency drive circuit of using at present forms the realization of auto-excitation type high frequency drive circuit by resolution element such as electric capacity, resistance, power field effect pipe.There is following shortcoming in the driving circuit of HF lamp without electrodes that discrete component is made:
(1) the drive signal amplitude size is unstable, so that power field effect pipe can not be in optimum Working, power dissipation is large, and heating is large, and light efficiency is low.
(2) frequency drift is serious, causes quality unstable, does not reach life expectancy.
(3) the drive circuit debugging trouble that is comprised of discrete component is made difficulty, and failure rate is high, and technical indicator is low, and cost is high.
Summary of the invention
The objective of the invention is to be to overcome the prior art deficiency, a kind of HF lamp without electrodes independent-excited driver circuits for integrated circuit is provided, purpose of the present invention realizes by following technical proposals: the present invention includes integrated circuit block, driving transformer, field effect transistor, printed circuit board (PCB) and aluminium heating panel, it is characterized in that: 6 pin of integrated circuit block 74hc04 are by printed circuit and field effect transistor Q1 and driving transformer T with by Q2, the half-bridge circuit that Q3 forms connects successively and forms, described integrated circuit block 74hc04, driving transformer T, field effect transistor Q1, Q2, Q3 is installed in independently one printed circuit board (PCB), Q2, Q3 closely is fixed on the aluminium heating panel.
Consider drive circuit stability of the present invention, on heat-dissipating aluminium plate, whole components and parts embeddings are become a capsule with casting glue, form independently thick mould drive circuit.
Principle of the present invention is to consist of the 2.65Mhz high frequency signal generator by integrated circuit 74hc04, and export small-power field effect transistor Q1 to by 6 pin and carry out signal and amplify, this driving signal is added to high-power FET Q2 by driving transformer T, on the Q3, by Q2, the half-bridge circuit output 2.65Mhz high-frequency high-power electric current that Q3 forms.The objective of the invention is as can be known to realize from above-mentioned situation.
The present invention is integrated circuit (IC) chip, signal driver field pipe, and driving transformer, power field effect pipe, radiator consist of thick mould one drive circuit.Described circuit can overcome the shortcoming of prior art, and assurance system long-term stability is worked efficiently, reduces cost, is easy to large-scale production.Advantage of the present invention is to adopt the independent-excited driver circuits for integrated circuit, has well solved the HF lamp without electrodes frequency drift, and the drive signal amplitude size is unstable, make difficulty, failure rate is high, and technical indicator is low, the high in cost of production defective has improved the quality of product, has reduced the cost of product.
