Discharge cell
As figure three, discharge cell of the present invention comprises discharge resistance RA, switching tube V2, series inductance L, current sensor T, sustained diode 6, absorbs back D5/RB/C5, electric current hysteresis comparator R1/R2/R3/R4/IC1, protection drive IC 3/C1/C2/R6/R7/R10/D1/D2/D7, the manually given R11/W1 of electric current, hand/change automatically R13/V3/D3/K1, manually parallel-current fine setting W2, parallel-current fine setting W3, wave filter automatically.
The total discharge resistance RA of foregoing circuit, switching tube V2, series inductance L, current sensor T are series relationship, are main current loop; Electric current hysteresis comparator, protection drive, electric current is given is series relationship, and this three parts series connection back is in parallel with main current loop.
Hysteresis comparator is realized current mode PWM modulation.
The discharge current I of the inductance L of flowing through
LBy current sensor senses, be output as and I
LProportional feedback current I, the comparison electric current that feedback current and electric current are given is delivered to hysteresis comparator inverting input and in-phase input end respectively.
After the given comparison electric current of electric current was determined, hysteresis comparator had two thresholding current potentials, Upper threshold h1 and Lower Threshold h2.When feedback current reaches h1, hysteresis comparator output low level VL, the 3 pin output low levels of protection drive integrated circult IC3, IGBT turn-offs, and inductive current reduces gradually.When feedback current drops to when being slightly less than h2, hysteresis comparator output high level VH, the IGBT conducting, discharge loop is connected, and inductive current strengthens gradually, and feedback current increases gradually.Therefore make comparative voltage reach h1 once more again, IGBT turn-offs once more ...Thereby, realize control to discharge by detecting inductive current.
The realization of constant-current discharge
By above-mentioned analysis as can be seen, the electric current set-point of hysteresis comparator is determined once given h1, h2, and inductive current i
LMAXBe proportional to h1, i
LMINBe proportional to h2.The hysteresis band Δ h of hysteresis comparator is determined by circuit parameter, does not change with h1, h2.So Δ i

CChange up and down, amplitude of fluctuation is Δ i
LJust obtain constant discharge current with filter capacitor after level and smooth.
Discharge cell has manual and automatic control function, and when manually the conversion and control level was high level automatically, discharge mode was manual discharge mode, and when manually the conversion and control level was low level automatically, discharge mode was automatic discharge mode; When discharge cell uses separately, manual discharging function can be used, when discharge cell and monitoring unit use simultaneously, automatic function can be used.
