Currently, the distinct device in military project, medical treatment and scientific research, such as electromagnetic launch, electroplating power supply, medical sterilization and food fresh keeping side
Face requires the support of the pulse power, with the development of technology, pulse voltage width of the various novel loads to pulse power supply
More stringent requirements are proposed for value, stability of waveform etc..
LCC Series- Parallel Resonant Converter is a kind of canonical topology applied to high-voltage DC power supply, by utilizing distribution electricity
Hold the Sofe Switch realized in the case of full load, to improve the working efficiency of converter.But its amplitude-frequency characteristic is by switching frequency and bears
Carrying size influences, under wider working range, it is difficult to good dynamic response is obtained, especially in wide gain and load change
In biggish operating condition, LCC controlled resonant converter dynamic response is slower, and stable state accuracy is low or even output voltage is unstable.
Classical PI control method is error-driven, is influenced by integral element, and under above-mentioned operating condition, only output voltage goes out
After existing obvious deviation, the feed-back regulatory mechanism of PI control can just come into force, and in addition to the response to power waveform has delay, lead to mother
Line voltage drop is outer, and the transient process that PI controls lower output voltage also results in certain fluctuation and overshoot, and these voltages
Temporal variations can be all reflected in the pulse voltage waveform of output, cause to require stringent answer in the fluctuation range to output voltage
With in scene, the application of traditional control method is greatly limited.
The key feature of controlled resonant converter is that there are high frequencies, the resonance potential of amplitude, electric current at resonant cavity, is effectively controlled
These high-frequency resonant behaviors are to improve converter dynamic response, reduce passive device and transformer electric stress and improve converter
The key of reliability.
In terms of energy viewpoint, the fluctuation of converter output voltage, be substantially due to transimission power and bearing power not
Caused by matching, fluctuation occurs in bearing power and the transimission power of converter is not adjusted in time, it is superfluous in transimission power or

Then transient state track is PN-PO-NO-NP, if SPO.end≤Rnew, according to SPO.endCalculate the track PP final value SPP.endIf SPP.end≥
Rnew, then transient state track is PN-PO-PP-NP, otherwise switches switching configuration in PP terminal, restarts temporarily into the lower half period
The judgement of state track.
The transient power adjusts that control algolithm is constant in output voltage and the size of bearing power is since pulse load is sent out
When raw big ups and downs, according to switching frequency corresponding to the switching frequency before variation, the power after variation, associative transformation device is set
The output voltage reference value of parameter and converter is counted, calculating adjusts the transimission power of converter to new along time optimal track
