Description

Technical Field

[0001] This utility model relates to the technical field of electrical components. Background Technology

[0002] Existing voltage boosting devices are mainly based on coil inductance boosting structures, which require a large amount of copper, high-quality inductor cores, and relatively complex drive circuits. They also suffer from significant electromagnetic radiation and low conversion efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a plasma variable capacitor boost device. This invention aims to overcome the problems of existing coil mutual inductance boost structures, which require a large amount of copper material, high-quality mutual inductance cores, and relatively complex drive circuits, while also exhibiting a large amount of electromagnetic radiation and low conversion efficiency.

[0004] This utility model discloses a plasma variable capacitor booster device, which includes a first conductive electrode 1, a second conductive electrode 2, a first dielectric 3, a second dielectric 4, and a gas 5.

[0005] The right end face of the first conductive electrode 1 is tightly connected to the left end face of the first dielectric 3, and the left end face of the second conductive electrode 2 is tightly connected to the right end face of the second dielectric 4. A gap 5-1 is provided between the right end face of the first dielectric 3 and the left end face of the second dielectric 4. Gas 5 is provided in the gap 5-1. Gas 5 is an inert gas. The whole structure forms a capacitor consisting of the first dielectric 3, gas 5, and second dielectric 4 connected in series. The first conductive electrode 1 and the second conductive electrode 2 are the two electrodes of this capacitor.

[0006] The positive terminal of the DC power supply 6 output is connected to the positive terminal of diode D1. The negative terminal of diode D1 is connected to the positive terminal of the first conductive electrode 1 and the positive terminal of diode D2. The negative terminal of the DC power supply 6 output is connected to the second conductive electrode 2. The negative terminal of diode D2 and the second conductive electrode 2 are high voltage output terminals. The output voltage of the DC power supply 6 must be greater than the breakdown voltage of the gas 5 in the gap 5-1 through glow discharge. When the DC power supply 6 charges the first conductive electrode 1 and the second conductive electrode 2 through diode D1 in the initial stage, it can break down the gas 5 in the gap 5-1 through glow discharge. The first dielectric 3 and the second dielectric 4 are both dielectrics with high dielectric constant.

[0007] This invention relates to a plasma variable capacitor booster device. Because it can use a high dielectric constant dielectric, such as barium titanate, its series capacitance can be very large during glow discharge of gas 5, reaching the uF level or larger. When gas 5 is in an insulating state, its series capacitance is less than the capacitance of gas 5, achieving a large-scale change in capacitance and thus a significant boosting effect. It has the advantages of saving copper, light weight, simple structure, low cost, and energy saving and environmental protection. Attached Figure Description

[0010] Specific implementation method one: Combining Figure 1 , Figure 2 This embodiment describes a first conductive electrode 1, a second conductive electrode 2, a first dielectric 3, a second dielectric 4, and a gas 5.

[0011] The right end face of the first conductive electrode 1 is tightly connected to the left end face of the first dielectric 3, and the left end face of the second conductive electrode 2 is tightly connected to the right end face of the second dielectric 4. A gap 5-1 is provided between the right end face of the first dielectric 3 and the left end face of the second dielectric 4. Gas 5 is provided in the gap 5-1. Gas 5 is an inert gas. The whole structure forms a capacitor consisting of the first dielectric 3, gas 5, and second dielectric 4 connected in series. The first conductive electrode 1 and the second conductive electrode 2 are the two electrodes of this capacitor.

[0012] The positive terminal of the DC power supply 6 output is connected to the positive terminal of diode D1. The negative terminal of diode D1 is connected to the positive terminal of the first conductive electrode 1 and the positive terminal of diode D2. The negative terminal of the DC power supply 6 output is connected to the second conductive electrode 2. The negative terminal of diode D2 and the second conductive electrode 2 are high voltage output terminals. The output voltage of the DC power supply 6 must be greater than the breakdown voltage of the gas 5 in the gap 5-1 through glow discharge. When the DC power supply 6 charges the first conductive electrode 1 and the second conductive electrode 2 through diode D1 in the initial stage, it can break down the gas 5 in the gap 5-1 through glow discharge. The first dielectric 3 and the second dielectric 4 are both dielectrics with high dielectric constant.

[0013] Working principle: Before charging, the capacitance of the capacitor connected in series with the first dielectric 3, gas 5, and second dielectric 4 is minimal because the dielectric constant of gas 5 is 1. When both the first dielectric 3 and the second dielectric 4 are made of barium titanate, the dielectric constant of barium titanate is around 3000. Therefore, the series capacitance is less than the capacitance of gas 5. Since the capacitance of the dielectric is much greater than that of gas 5, when the DC power supply 6 charges the first conductive electrode 1 and the second conductive electrode 2 through diode D1, according to the principle of voltage division, the larger the capacitance, the smaller the voltage drop, and vice versa. Therefore, the voltage drop across the dielectric layer is very small. Most of the voltage will fall on gas 5, thus making its voltage greater than the breakdown glow discharge voltage of gas 5 (by setting the output voltage of DC power supply 6, adjusting the spacing of gap 5-1, and adjusting the pressure of gas 5, so that the breakdown glow discharge voltage of gas 5 is less than its voltage divider voltage). When gas 5 breaks down into plasma glow discharge, gap 5-1 is approximately electrically short-circuited—the capacitance value is approximately infinite, that is, the first dielectric 3 and the second dielectric 4 are directly and approximately electrically short-circuited, thus causing the overall series capacitance value to increase rapidly, approaching the capacitance value of the direct series connection of the first dielectric 3 and the second dielectric 4. The glow discharge of gas 5 then enters the maintenance phase. In the photodischarge state, while continuing to charge, when the capacitor connected in series with the first dielectric 3 and the second dielectric 4 reaches the output voltage value of the DC power supply 6, it is fully charged and will stop charging. No current flows, causing the voltage drop across gas 5 to fall below the sustaining voltage of the glow discharge, thus extinguishing the glow discharge. At this point, gas 5 returns to its gas-insulating state, causing the capacitance of the capacitor connected in series with the first dielectric 3, gas 5, and the second dielectric 4 to return to its minimum value. According to the principle of charge conservation in capacitors, the charge remains constant, the capacitance decreases, and the voltage increases. At this time, the voltage between the first conductive electrode 1 and the second conductive electrode 2... The voltage between the first conductive electrode 1 and the second conductive electrode 2 rises rapidly, exceeding the output voltage of the DC power supply 6, thus boosting the voltage. Due to the presence of diode D1, it cannot discharge in reverse to the DC power supply 6; it can only discharge externally through diode D2. Because the series capacitance is very small at this time, most of the charge is transferred out through diode D2, causing the voltage between the first conductive electrode 1 and the second conductive electrode 2 to drop rapidly. When the voltage drops below the output voltage of the DC power supply 6, the DC power supply 6 will recharge the first conductive electrode 1 and the second conductive electrode 2 through diode D1, causing the gas 5 to break down and discharge with a glow discharge, thereby achieving a recurring cycle of high voltage output to the outside. The entire device can be housed in an insulated, sealed container.
