Definitions
- Pulse power supply that regenerates magnetic energy
- the present invention relates to a pulse power supply for supplying a pulse current to an inductive load.
- a high-voltage charged energy source capacitor which supplies a large current to an inductive load, is connected to the load using a semiconductor such as an ignitron, a discharge gap switch, or a thyristor as a switch. Therefore, a pulse power supply for starting a capacitor discharge is generally used.
- These discharge switches usually have a diode called a clamp circuit connected in parallel with the load or in parallel with the capacitor.After the current reaches its maximum, the diode turns on with the reversal of the capacitor voltage, and the load turns on. The current circulates through the diode, preventing reverse charging of the capacitor, and the clamped current continues to attenuate with the time constant LZR due to the electrical resistance of the load.
- Pulsed high-field bending electromagnets of small medical synchrotron accelerators need to operate in such a way that the magnetic field rises with time rather than using the maximum magnetic field. It is required to increase the pulse rate. Also, in the case of a gas-excited laser power supply, high-speed voltage rise and high repetition are required, and high repetition control is required as a discharge power supply. I was
- FIG. 2 is for explaining the basic operation of the present invention.
- the power supply has a snubber-energy regeneration type current switch.
- the capacitor that temporarily stores the snubber energy corresponds to the energy source capacitor in the present invention.
- Japanese Patent Laid-Open No. 2000-358359 "Current forward / reverse bidirectional switch for regenerating snubber energy" discloses a current switch of a snubber energy regeneration system (Patent Document 1).
- Patent Document 1 discloses that the magnetic energy of the breaking current circuit is temporarily stored in the snubber capacitor. To be released to the load at the next conduction It is a current switch.
- the energy source capacitor is charged with all the energy, and the load is driven only by the energy. At the end of the pulse, the magnetic energy remaining in the load is regenerated to the energy source capacitor. The point to try is different from that described in Patent Document 1.
- the load is an inductive load, which is represented by resistance R and inductance L.
- R resistance
- L inductance
- capacitor 1 is charged as shown in Fig. 2 (charging circuit is omitted), and when switch S1 and switch S2 are turned on, the charge of the capacitor starts to flow to the load.
- the load current circulates through the diode, enters a freewheeling state, and the load current is written as “the path through which the main current flows”. In two directions in the same direction.
- the discharge can be started, maintained, and reduced by turning on and off the switch at an arbitrary timing, and the magnetic energy is applied to the capacitor with the same polarity. It is regenerated.
- FIG. 4 is a principle diagram for developing the present invention bidirectionally.
- FIG. 2 This figure differs from Fig. 2 in that four units connected in parallel with a diode and a switch are mounted in anti-series and anti-parallel as shown in the figure, so that bidirectional current can flow to the load. The point is that magnetic energy is regenerated in the capacitor 1 when the switch is turned off (the charging circuit is omitted here as in Fig. 2).
- FIG. 5 shows a simulation circuit and a waveform of the result showing that the energy supply to the energy source capacitor 1 can be supplemented by the low-voltage / high-current power supply 5 inserted in the discharge circuit.
- the voltage and load current increase with the number of discharges. This is because the discharge current increases when a voltage higher than the DC resistance is injected from an external power supply.
- the current value of the pulse current can be controlled by increasing or decreasing the voltage of the external power supply.
- FIG. 1 is a diagram for explaining an embodiment of the present invention.
- FIG. 2 is a diagram illustrating the basic principle of the present invention.
- FIG. 3 is a diagram for explaining the sequence of the current, voltage and switch shown in FIG.
- FIG. 4 is a diagram for explaining the basic principle of the current bidirectionalization of the present invention.
- FIG. 5 shows a computer simulation model diagram for analyzing the basic principle of the method for assisting the capacitor voltage of the present invention, and a simulation waveform of the load current and the capacitor voltage.
- FIG. 1 is a circuit diagram showing an embodiment of the present invention.
- Fig. 4 differs from Fig. 4 in that, when a deflection electromagnet 6 for an accelerator, which is a specific example of a load, is excited by a pulse current via a current transformer 3, four power MOS FETs are connected in reverse series and anti-parallel. This is where it is configured with a connection. As a result, the four power MOS FETs constitute a bridge circuit.
- the power MOS FET used here has a high breakdown voltage, turns on and off quickly, and has conduction loss. It is assumed that the power MOSFET is a silicon-powered (SiC) power MOS FET that has few features and that a body-to-body diode (also called a parasitic diode) can be used effectively as a substitute for a parallel diode.
- SiC silicon-powered
- the effect of the present invention can also be exerted in a reverse conducting GTO thyristor, or in a unit in which a diode and a semiconductor switch such as an IGBT are connected in parallel.
- a switch that does not flow (block) current in the forward direction when the switch is off, but conducts in the reverse direction is called a reverse conduction type semiconductor switch.
- Examples thereof include the power MOS FET, the reverse conducting GTO thyristor, and a unit in which a diode is connected in parallel with a semiconductor switch such as an IGBT.
- a gate signal is given to the G1 to G4 from the control device 7 to the power MOS FET switch shown in FIG. 1, but the direction of the current can be changed by selecting a pair for "crossing" of Gl and G2. The direction becomes forward, and when the pair G 3 and G 4 is selected, the direction of the current becomes reverse. This is necessary to enable the flow of magnetization reset current for improving the excitation characteristics of the current transformer for pulse operation of a small medical accelerator bending electromagnet. '
- a low-voltage high-current power supply 5 is inserted between the inductive load 6 and the switch 2. By applying this voltage in series to the discharge current, the energy is discharged every discharge. Can be replenished.
- the capacitor 1 can be charged like a snubber capacitor. Without preparing another high-voltage power supply, it is possible to obtain a fast-start pulse current with only a low-voltage power supply. Mochi Of course, the general method of connecting a charging power source to the capacitor 1 and charging the capacitor is also effective. Industrial applicability
- the gate signal of the bidirectional current switch having a bridge configuration composed of four semiconductor switches connected in parallel with a diode is used as the switch of the current generating energy source capacitor.
- the current to the inductive load can be started, maintained, and stopped at high speed.
- magnetic energy is regenerated to the capacitor with the same polarity.
- the charge voltage of the capacitor can be increased or decreased while repeating the discharge cycle.
- the total capacitance of the four switch elements can be halved individually if the withstand voltage is given in two series of power MOS FETs, and the pulse conduction current flows in two arms in parallel. In consideration of the above, this is also half, so that it can be handled basically without increasing the voltage and current capacity as compared with the conventional pulse power supply.
