The front part of a booster transformer T2 in an old R-C charge mold circuit is inserted with a voltage regulator T1 in the circuit of the utility model, and an electric motor is used for driving the voltage regulator to boost automatically to generate dynamic direct-current charge voltage from low to high for charging an energy storage capacitor. The utility model has the advantages of high charge efficiency, anti-jamming and strong capacity of overload resistance of the circuit, and the utility model is suitable for occasions with low repetition rate, large charge energy and high output voltage.
Description
The utility model relates to the Laser Power Devices technology.
The charging modes of existing pulsed ruby laser power supply has two kinds: first kind is old-fashioned RC charge mode, its circuit as shown in Figure 1: be typical bridge rectifier charging circuit.Wherein T2 is a step-up transformer, and line voltage is raised to the required magnitude of voltage of energy-storage capacitor C2.
The magnitude of voltage that the flashlamp discharge of laser is required.Capacitor C1 is the filter capacitor after the full-wave rectification, plays the smooth voltage fluctuation; Resistance R is the charging resistor that current limliting is used; Capacitor C2 is the energy-storage capacitor that is recharged.Its shortcoming is: the output of step-up transformer T2 is a fixing high pressure, thereby must produce thermal losses with charging resistor R restriction charging current.Charge efficiency has only 50%.Though sort circuit is simple in structure, charging rate is very low, and energy loss is big and bring the trouble of heat radiation.Second kind is new-type Switching Power Supply, its charge efficiency height, volume is little, control also very convenient, but cost height, overload and poor anti jamming capability.
The purpose of this utility model is, a kind of shortcoming that overcomes existing Laser Power Devices is provided, the charge efficiency height, and overload and antijamming capability are strong, simple in structure, the voltage regulator formula pulse laser power supply that cost is low.
The schematic diagram of the utility model power supply such as accompanying drawing 2 relatively have following characteristics with the charging circuit of old-fashioned R-C charge mode, and 1. the electrical network input inserts voltage regulator T1, has 2. omitted filtering capacitor C1. and has 3. omitted charging resistor R.Its course of work is as follows: the input of T1 is line voltage 220V, and it is adjustable to be output as 0-240V.T2 is a step-up transformer, the output voltage of voltage regulator is elevated to satisfies the required magnitude of voltage of energy-storage capacitor.
Charging process of the present utility model and old-fashioned R-C charge mode difference are; The output of step-up transformer T2 is not a fixing high pressure, so filter capacitor C1 can omit.The output voltage that the improving constantly of the output voltage of voltage regulator makes the transformation T2 that boosts is also by low high, thereby realize the charging to energy-storage capacitor C2, charging current is proportional to voltage build-up rate, need not limit charging current with charging resistor R, thereby do not produce thermal losses, charge efficiency is near 100%.Drive voltage regulator by motor and rotate the variation from low to high that realizes the voltage regulator output voltage.
Outstanding advantage of the present utility model is:
1, the charge efficiency height has been carried one times than the efficient of existing RC charging circuit, and method is simple, economy;
2, owing to the elements of having avoided using in the Switching Power Supply such as semiconductor switch pipe, the overload capacity of circuit strengthens greatly, has improved the reliability of power supply;
3, antijamming capability is strong;
4, be particularly suitable for the occasion of repetition rate low (several seconds are once) rechargeable energy big (more than each energy storage kJ (kilojoule)) and output voltage height (greater than 1500V).
Below in conjunction with accompanying drawing, describe the utility model in detail.
Accompanying drawing 1 is old-fashioned R-C charging circuit.
Accompanying drawing 2 is the utility model circuit diagrams.
Circuit of the present utility model is as shown in Figure 2. and insert voltage regulator T1 before step-up transformer T2, step-up transformer T2 meets capacitor C2 again through full-wave rectification, two ends charged in parallel measuring circuit and the capacitor discharging circuit of C2.Motor A and voltage regulator T1 are coaxial.Voltage regulator T1 is driven by motor A, realizes the dynamic rising of output voltage, export a constantly alternating voltage of rising, and this voltage becomes direct current and then meets energy-storage capacitor C2 it is charged through the step-up transformer T2 full-wave rectification again of boosting.The two ends charged in parallel measuring circuit (resistor voltage divider circuit and ammeter) of C2 and capacitor discharging circuit (reverse-blocking tetrode thyristor and xenon lamp).Charging measuring circuit and capacitor discharging circuit all are known circuits.The course of work of the present utility model is, the input of voltage regulator T1 is from line voltage 220V, and it is adjustable to be output as 0-240V, and motor A drives the voltage regulator rotation and realizes boosting automatically; Step-up transformer T2 raises the output voltage of voltage regulator (noticing that the voltage output of T2 is from the zero initial necessary high voltages that progressively rises to), becomes direct current output through full-wave rectification.The charging voltage of energy-storage capacitor C2 can be regulated in the 0-2000V scope.
