With.High-power modular inverter/converter platform is required in current EHV electric and hybrid vehicle developmental research,
These realize in the inverter platform of DC/AC conversion that high density capacitors play very crucial effect.Current inverter
Middle dc-link capacitance and buffering electric capacity usually require the larger polymer thin membrane capacitance and alminium electrolytic condenser of capacitance, due to this
A little capacitors are bulky, account for the volume of the nearly half of inverter module, the miniaturization to these inverters brings difficulty.If adopting
Aluminium electrolutic capacitor is substituted with the microcrystalline glass capacitor of high energy storage density, control unit volume will be greatly reduced.In addition, in arteries and veins
Rush in power apparatus, also occupy very big proportion as the energy-storage capacitor of critical component, the capacitor of existing foil structure is present
Energy storage density is low, break down after the defect such as explosive, also will be effective if using this new high density capacitors
Ground reduces the volume of great power pulse power source.In terms of the energy supply of some medical devices of implantation human body, this superelevation storage
The capacitor of energy density also has important application.
Develop dielectric material of glass-ceramics with high energy storage density, it is necessary to dielectric constant should be made big as far as possible, while again
Ensure high breakdown field strength.Although the dielectric constant of ferroelectric crystalline phases is very big, disruptive field intensity is relatively low；Although and glass phase breakdown field
It is strong very high, but dielectric constant is general all smaller.The preparation method of current ferroelectric glass-ceramic mainly includes overall crystallization method, burnt
Connection and sol-gel process.Overall crystallization method is a kind of the more commonly used method for preparing devitrified glass.It can obtain crystal grain
The devitrified glass sample of tiny and even structure, high compaction.This method also have a feature be can continue to use glass calendering,
Compacting, casting forming method obtain the thin slice for meeting size requirement.In the stages such as sheet glass is formed through nucleus again, crystal growth, make
Glass Transition is with the sub-micron even devitrified glass of nanocrystalline grain size.The shortcoming of this method is to be less susceptible to crystallization,
Ferroelectricity is with dielectric properties by glass mutually undue dilution and weakening；Sintering process is by the batch of certain component, through high temperature melting, clear
Clearly, be homogenized, cool down, then through water quenching into certain granules size glass particle, it is then thin through ball milling is levigate, shaping prepares base substrate
Piece.Last sintered, crystallization obtains sample.More or less all there is stomata in sample prepared by this method, for preparing is micro-
The compactness of crystal glass is poorer than overall crystallization method.Sol-gel process is a kind of low temperature synthesis process, is by the Organic Alcohol of metal
Salt is sintered as precursor, through hydrolyzing to form gel, then at a lower temperature, obtains devitrified glass.This method is prepared in material
Initial stage be just controlled, material homogeneity is high, has the disadvantage to have larger contraction in sintering process, is easily deformed.
