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,

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.
