Description
Technical Field
The invention relates to a voltage establishing device and method for an analog voltage doubling circuit, and belongs to the technical field of voltage establishing process simulation.
Background
With the development of power electronic technology and the emergence of new high-performance, high-voltage-withstanding and high-frequency power electronic devices, high-voltage direct-current power supplies are beginning to be widely applied in military, industry, agriculture, medical treatment and daily life. At present, the most common method for generating the direct current high voltage is a half-wave rectification method formed by a high-voltage transformer with a high turn ratio, a direct current high-voltage silicon stack and a high-voltage capacitor, however, in practical application, the too large turn ratio of the transformer aggravates the nonideal of the transformer, the nonideal causes the problems of peak voltage and current of the transformer, the overlarge volume of the transformer and the like, and the limitation of the rated voltage and the capacity of the high-voltage silicon stack and the high-voltage capacitor is also caused. In each technical scheme of the high-voltage power supply, the cascade direct-current high-voltage generator has the advantages of simple circuit structure, capability of effectively reducing the volume of a transformer and the like, and is widely applied to high-voltage low-current circuit occasions. The voltage doubling circuit is a basic unit forming the cascade direct-current high-voltage generator, and understanding of the voltage establishment process of the voltage doubling circuit is a premise for understanding of the working principle of the cascade direct-current high-voltage generator. In addition, the high voltage test technology is a course which is necessary for the department of the high voltage and insulation technology in China, and the voltage doubling circuit is the key content which must be mastered by students, but the working principle of the circuit is obscure and unintelligible, so that the students are easy to misunderstand. For researchers, most of the researchers are studying the output voltage waveform and the circuit working efficiency on the basis of the voltage doubling circuit, and the research on the working principle of the voltage doubling circuit is less, and even the basic principle does not have a clear concept. The voltage doubling circuit is shown in fig. 5, and according to the node marked in the figure, U30 is the output voltage of the test transformer; u13 is the potential difference between the upper and lower electrode plates of the capacitor C1; u10 is the reverse voltage of the high-voltage silicon stack D2; u20 is the voltage between the upper and lower plates of the capacitor C2 and is also the output voltage. The potential variation of each point in the charging process of the voltage doubling circuit is shown in fig. 6. The working principle of the circuit is as follows: the test transformer T is connected with an alternating current power supply. When the voltage waveform rises to a positive peak value from a zero point, the high-voltage silicon stack D1 is switched on, the D2 is switched off, the test transformer charges the C1 capacitor, the potential of the 3 point is + Um, the potential of the 1 point is 0, the voltage of the two ends of the U13 is-Um, the C1 capacitor and the C2 capacitor are charged in series, the voltage of the two ends of the U13 is-Um/2 after charging, and the voltage of the two ends of the U20 is increased to + Um/2 from 0. When the voltage waveform is reduced from the positive peak value to approach the negative peak value, the high-voltage silicon stack D1 is cut off, the high-voltage silicon stack D2 is conducted, the test transformer charges the capacitor C1, but the capacitor C1 does not charge the capacitor C2, and the voltage at the two ends of the U13 is increased from-Um/2 to + Um. When the input voltage waveform rises from a negative peak value to approach a positive peak value, the high-voltage silicon stack D1 is switched on, the high-voltage silicon stack D2 is switched off, and the C1 capacitor and the C2 capacitor are continuously charged in series. After the charging is finished, the voltage across the U13 is + Um/4, and the voltage across the U20 is increased from + Um/2 to +5Um/4. The voltage waveform continues to drop to a negative peak and the test transformer charges the C1 capacitor. When the voltage waveform rises to the positive peak value, the C1 capacitor and the C2 capacitor are charged in series, and the voltage at the two ends of the U20 is increased from +5Um/4 to +13Um/8. Analysis shows that the voltage of the U20 is increased gradually: 0 → + Um/2 → +5Um/4 → +13Um/8. This is repeated for a number of cycles, and finally the 2-point potential will reach +2Um, i.e. the U20 voltage will finally be equal to +2Um. The 2 point is a voltage output end of the voltage doubling circuit, and the output voltage of the voltage doubling circuit can reach 2 times of the output voltage amplitude of the test transformer, so that the voltage doubling circuit is called. From the perspective of the word description working principle, the working principle of the circuit is complex, the word description is tedious, and the beginner can hardly understand the circuit completely. However, if the working principle of the voltage doubling circuit is not deeply understood in the learning process, the voltage doubling circuit is difficult to be deeply researched and applied, so that it is necessary to develop a device capable of simulating the voltage establishment process of the voltage doubling circuit to help relevant scholars and students in schools to understand the working principle of the circuit.
In view of the above, it is desirable to provide a voltage setting apparatus for an analog voltage doubling circuit and a method thereof to solve the above-mentioned problems.
