The principle of charging and discharging of Teslaman capacitors and the introduction of related high-voltage power supply products
The principle of capacitor charging and discharging:
When the capacitor is connected to the power supply, under the action of the electric field force, the free electrons of the capacitor plate connected to the positive pole of the power supply will move to the plate connected to the negative pole of the power supply through the power supply, and the positive pole will be positively charged due to the loss of negative charge. The negative electrode is negatively charged due to the negative charge, and the charges on the positive and negative plates are equal in magnitude and opposite in sign. The directional movement of the charges forms a current. Due to the repulsion of the same-sex charges, the current is the largest at the beginning, and then gradually decreases. In the process of charge movement, the charge stored on the capacitor plates keeps increasing. When the voltage Uc between the two plates of the capacitor is equal to the power supply voltage U, the charge stops moving, the current I=0, the switch is closed, and the positive and negative plates of the capacitor are connected by the connection of the wires. neutralize. When K is closed, the positive charge of the positive electrode of the capacitor C can be moved to the negative electrode and neutralized, and the negative charge of the negative electrode can also be moved to the positive electrode and neutralized. The charge gradually decreases, the apparent current decreases, and the voltage gradually decreases to zero.
Teslaman TD2202 series is a high-performance 19” standard rack-mounted high-voltage power supply. It adopts digital control method to meet the functional requirements of various control settings of customers, and the nanosecond-level arcing transient response capability ensures that the power supply is trouble-free. Operation, the efficiency reaches more than 90%. This series of products has complete functions, wide output range, and can also add functions that customers need to customize through software.
Teslaman TLP2081 series is a liquid cooling high voltage capacitor charging power supply integrating oil cooling and water cooling. It is mainly used in electromagnetic emission, high energy microwave, laser fusion, MARX generator, strong particle beam and other fields. High pulse repetition accuracy and can be installed and fixed in any orientation are the distinctive features of this power supply. Its maximum average output power and peak power at rated voltage can reach 15kW.
TLP2081 adopts high frequency IGBT to form the main topology of parallel resonance and cooperates with perfect control circuit to form the whole system. In addition to adjusting the voltage, the control circuit also detects changes in load and temperature in real time, and takes corresponding protection measures. Advanced resonant main topology improves repetition accuracy at high repetition rates by reducing ripple. In addition, the high pressure water cooling box is specially designed for liquid circulation cooling. This special design allows the power supply to be installed and operated in any orientation. The TLP2081 series supply voltage can be adjusted over the entire range.
