The utility model discloses LC resonance charging source's theory of operation as follows:
Firstly, charging a primary capacitor Cp and an energy storage capacitor Cm, and when a specified voltage is reached, outputting a trigger signal by a trigger control module to enable a discharging thyristor switch S1 to be conducted; secondly, after the voltage on the primary capacitor Cp is boosted by a pulse transformer Xformer, a load capacitor Cload is charged through a high-voltage silicon stack D; thirdly, when the secondary output charging voltage of the pulse transformer Xformer reaches the highest value of the oscillation charging voltage, the gas Switch is triggered to be switched on, and the final load Rload is discharged; then, the primary capacitor Cp is discharged through a discharge thyristor switch S1, when the current flows through zero, the discharge thyristor switch S1 is cut off, the voltage value on the primary capacitor Cp is a negative value, at the moment, a central control system sends out a trigger pulse to enable an energy recovery thyristor switch S2 to be conducted, and the back pressure of the primary capacitor Cp is subjected to energy recovery through a loop Cp-S2-L1-L2-Cp; finally, after the energy of the primary capacitor Cp is replenished, the charging operation is completed, and the process returns to step S1.
In step S3, the trigger on time of the gas Switch is set to any time after the maximum value of the secondary output charging voltage of the pulse transformer Xformer is reached. Compared with the prior art, the conduction time is required to be set before the charging voltage of the pulse transformer Xformer reaches the maximum voltage of the secondary output, and the charging time of the pulse transformer Xformer is usually tens to hundreds of microseconds, so that the requirements on the conduction response time of the gas Switch on the load capacitor Cload, the response time of a Switch trigger system and the synchronization time are greatly reduced; in the energy recovery process of step S4, according to the voltage value of the energy storage capacitor Cm and the voltage value of the primary capacitor Cp, the central control system triggers the energy recovery thyristor switch S2 and the energy supplement thyristor switch S3 respectively through different pre-designed trigger timings, so that the voltage value of the primary capacitor Cp after energy recovery and supplement is equal to the initial charging voltage value.
In addition, since the polarity of the voltage on the primary capacitor Cp is negative opposite to the original voltage after the primary capacitor Cp is boosted by the transformer pulse transformer Xformer to charge the load capacitor Cload, the partial energy efficiency formula is as follows:
Wherein, CloadIs the capacitance value, U, of the load capacitor CloadcloadCharging voltage for load capacitor Cload, CpIs the capacitance value of the primary capacitance Cp, UCp0Is the initial charging voltage, U, of the primary capacitance Cpcp-back voltage for the primary capacitance Cp after one charging cycle.
According to the formula (1), the charging voltage U on the load capacitor Cload is obtainedcloadThe larger the back voltage U of the primary capacitor Cp after a charging cyclecpthe larger (or closer to U)Cp0) The higher the energy efficiency.
When the secondary output charging voltage of the pulse transformer Xformer reaches the highest value of the oscillation charging voltage, the gas Switch is triggered and conducted through the high-voltage silicon stack D to discharge the final load Rload, when the load voltage reaches the maximum value, the voltage on the load does not oscillate and discharge through the secondary coil loop of the transformer, and Ucloadcan be maintained at the highest value for a long time, and the efficiency of the power supply can be obviously improved.
In a further embodiment, the operating voltage range of the energy storage capacitor Cm for supplementing the voltage value of the primary capacitor Cp is calculated by the following formula:
In the formula of Ucmfor the voltage value, U, over the energy-storage capacitor CmcpBack voltage, U, for the primary capacitance Cp after a charging cycleCp0Is the initial charging voltage of the primary capacitance Cp.
Ideally, the maximum number of pulses output by the energy storage capacitor Cm is a ratio of the maximum effective energy of the energy storage capacitor Cm to the energy lost by the primary energy circuit in each period, and the maximum number of pulses is set to be N, which is expressed as:
in the formula, CmIs the capacitance value, C, of the energy storage capacitor Cmpis the capacitance value of the primary capacitance Cp, UCp0Is the initial charging voltage, U, of the primary capacitance CpcpBack voltage for the primary capacitance Cp after one charging cycle
It can be seen from the combination of the formula (2) and the formula (3) that, under the condition of driving by the energy storage capacitor Cm, the larger the reverse voltage value of the primary capacitor Cp is, the larger the effective voltage range of the energy storage capacitor is, and under the same capacitance value of the energy storage capacitor Cm, the output of more pulses can be realized.
The parameters of the LC resonant charging power supply were chosen as follows: the storage capacitor Cm is 20mF, the primary capacitor Cp is 1.2mF, the load capacitor Cload is 1 muF, the primary 5 muH, the secondary 4mH, the primary circuit equivalent resistance 5 mOmega, the secondary circuit resistance 3 omega, the coupling coefficient is 0.88 and the final load Rload1 omega of the pulse transformer Xformer. Assuming that the charging voltage required by the load capacitor Cload is 100kV, the charging voltage is 3900V at this time, the maximum charging voltage is 100kV, the on-time of the gas Switch is set to 350 μ S, the charging voltage of the load capacitor Cload is 100kV at this time, the back-pressure value of the primary capacitor Cp is-1803V, and the energy efficiency of the Cp-S1-Xformer-Cload loop is calculated as follows:
Therefore, the energy efficiency is calculated to be 69.7% according to the formula (1), the working voltage range of the energy storage capacitor Cm is calculated to be 1048V-2852V according to the formula (2), and the theoretical output pulse number is calculated to be 9.8 according to the formula (3).
The following are the energy efficiency and the number of output pulses under two conditions of no current increase of the high-voltage silicon stack:
In the first case, in order to improve the energy efficiency of the loop under the condition of not increasing the current of the high-voltage silicon stack, the triggering time of the gas Switch reaches the maximum output charging voltage of the secondary of the transformer. At the moment, 3900V is charged, the maximum time of the secondary output voltage of the transformer reaches 66.7 mu s, the conducting time of the gas Switch is set to 66.7 mu s, the load capacitor Cload reaches the maximum voltage of 100kV, the back pressure value of the primary capacitor Cp is-835V, the energy efficiency is 57.4% according to the formula (1), the working voltage range of the energy storage capacitor Cm is 1532V-2368V, and the theoretical output pulse number is only 3.74 according to the formula (3).
In the second case, under the condition of a high-voltage silicon stack without increasing current, in order to improve the working voltage range and the number of output pulses of the energy storage capacitor Cm, when the Switch trigger time reaches 80% of the maximum value of the secondary output charging voltage of the transformer, the primary capacitor is charged by 4680V, the maximum time of the secondary output voltage of the transformer reaches 66.7 μ s, the secondary output maximum charging voltage of the transformer reaches 120kV, the Switch on time is set to 48.3 μ s, the Cload charging voltage of the load capacitor is 100kV, the back pressure value of the primary capacitor Cp is-1965V, so that the energy efficiency is calculated to be 46% according to the formula (1), the working voltage range of the energy storage capacitor Cm is 1357V-3322V, and the theoretical number of output pulses is calculated to be 5.28 according to the formula (3).
By comparing the three conditions, the design method of the invention improves the energy efficiency of the loop, expands the voltage working range of the energy storage capacitor Cm and improves the maximum output pulse number of the energy storage capacitor Cm.
