What the present invention relates to is a kind ofly to regulate non-polar condenser based on the miniature of high dielectric material at system programmable, has the structure of parallel-plate.By utilizing the I/O interface of controller, cooperate suitable drive circuit in order to drive the controlled end of thyristor, the electric pole plate that connects different area above the parallel-plate with a main terminal of thyristor, another main terminal of thyristor is connected and draws terminals as parallel plate capacitor, lower electrode plate below the parallel-plate is drawn an end as another terminals of parallel plate capacitor, thereby realizes the non-polar condenser based on high dielectric material is carried out regulating and control at system programmable by writing the corresponding I/O of different driven by program controllers.
Operation principle of the present invention is:
Involved in the present invention regulate non-polar condenser based on the miniature of high dielectric material at system programmable, its essence is the size that can change corresponding parallel-plate area, namely after determining a kind of high dielectric fill material, but electric capacity opening relationships between two parallel-plates:
Wherein d is polar plate spacing,
Be permittivity of vacuum,
For the dielectric relative dielectric constant, be all definite value.S is relative area between pole plate, so:
Wherein, A is a definite value, and is final, can realize controlled output to capacitance by the corresponding area S of in-system programming control break parallel-plate.
The invention has the advantages that: in use come in the adjustment of system's realization to the capacitance size by the electric pole plate area that makes up different sizes, parallel connection by the different parallel plate capacitor of N capacity can be combined into other capacitor of different capabilities level, adopt this structure, can save the material of making required different capabilities rank capacitor.The capacitor volume value can be by the method adjustment of in-system programming, avoid the improper work that repeats of changing different capacitors repeatedly that causes of condenser capacity in the circuit, have the advantages that volume is little, capacity is big, easy to adjust, recycling can the regulating capacitor capacity can economize on resources again.
