Description

Series resonance converter plant
Technical field
The present invention relates to a kind of Equipment for Heating Processing, more particularly to a kind of series resonance converter plant.
Background technology
Need to use series resonance converter plant, series resonance frequency conversion dress in casting, forging and heat treatment industry The structure put mainly includes:Power supply, load is arranged in series with positive source, the resistance set with load in series, The inductance of setting in series with a resistor, the positive pole of the inductance and electric capacity is arranged in series, the negative pole of the electric capacity with Power cathode is arranged in series, and originally power supply is all that circuit is powered using current source, humorous in circuit connected in series During shaking, because current source internal resistance itself is larger and is parallel-connection structure with current source, current source is supplied to The electric current of load can disperse quite a few to current source internal resistance itself, cause useless power big, available power Small, a current source can only drive a load to be operated in each casing, and inefficiency such as needs band Many loaded work pieces are moved, it is necessary to be powered using multiple casings and multiple current sources, space-consuming is big, makes With trouble.
The content of the invention
The technical problems to be solved by the invention are:A kind of series resonance converter plant occupied little space is provided.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is:Series resonance converter plant, Including:Casing, is arranged on the voltage source in casing, the first load being arranged in series with voltage source positive pole, with The second load that first load in series is set, the 3rd load set with the second load in series, with the 3rd load The resistance being arranged in series, the inductance of setting in series with a resistor, the positive pole of the inductance and electric capacity is arranged in series, The negative pole of the electric capacity and the negative pole of voltage source are arranged in series, and the structure of the voltage source includes:Power supply body With the internal resistance of source being arranged in series with body.
It is an advantage of the invention that:Above-mentioned series resonance converter plant, is powered using voltage source to circuit, During circuit connected in series resonance, voltage source internal resistance itself is smaller, and the idle work done is small, can will be big Portion of electrical current is supplied to load, and active power can reach in more than 98%, each casing that a voltage source can be with Three loads are driven to be operated, operating efficiency is high, occupies little space.
Brief description of the drawings
Fig. 1 is the structural representation of series resonance converter plant of the present invention.
Fig. 2 is structural representation when series resonance converter plant of the present invention uses voltage source.
In figure:1st, casing, 2, voltage source, 21, power supply body, 22, the internal resistance of source, the 3, first load, 4th, the second load, the 5, the 3rd load, 6, resistance, 7, inductance, 8, electric capacity.
Embodiment
The particular content of the present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, series resonance converter plant, including:Casing 1, is arranged in casing 1 Voltage source 2, the first load 3 being arranged in series with the positive pole of voltage source 2, the be arranged in series with the first load 3 Two loads 4, the 3rd load 5 being arranged in series with the second load 4, the resistance being arranged in series with the 3rd load 5 6, the inductance 7 being arranged in series with resistance 6, the positive pole of the inductance 7 and electric capacity 8 is arranged in series, the electricity The negative pole for holding 8 negative pole and voltage source 2 is arranged in series, and the structure of the voltage source 2 includes:Power supply body 21 and the internal resistance of source 22 that is arranged in series with body 21.
Above-mentioned series resonance converter plant in use, due in casing 1 voltage source 2 and resistance 6, inductance 7, The load of electric capacity 8, first 3, second load 4 and the 3rd load 5 are arranged in series, and occur series resonance in circuit When, according to Ohm's law, I=U/ | Z |,ω L and For frequency function, when frequency is relatively low, the capacitive reactance of circuit is big and induction reactance is small, the impedance of circuit | Z | it is larger, Electric current is smaller;When frequency is higher, the induction reactance of circuit is big and capacitive reactance is small, the impedance of circuit | Z | it is also larger, Electric current is also smaller.Between both frequencies, always having some frequency makes the capacitive reactance of circuit and induction reactance lucky It is equal.At this moment the impedance of circuit is minimum, so electric current is maximum.Due to the impedance of the internal resistance of source 22 of voltage source 2 It is smaller, and the internal resistance of source 22 and power supply body 21 are cascaded structure, the idle work that the internal resistance of source 22 is consumed is very It is small, most of electric current can be supplied to load, electric current reaches maximum in series resonance, and first negative Carry the 3, second load 4 identical with the electric current of the 3rd load 5, the available power of circuit can reach more than 98%, One voltage source 2 can drive three loads, occupy little space.
Above-mentioned series resonance converter plant, is powered using voltage source to circuit, in circuit connected in series resonance During, voltage source internal resistance itself is smaller, and the idle work done is small, can be supplied to most of electric current negative Carry, active power can reach that a voltage source can drive three load progress in more than 98%, each casing Work, operating efficiency is high, occupies little space.
