Embodiment
As shown in Figure 1, a kind of charge protector of kitchen range cogeneration, it comprises a charging control circuit 1 of mainly being made up of several triodes and resistance; One current potential comparison circuit 2 mainly is made up of potential comparator and several resistance, judges going forward side by side and charging circuit is controlled when the prepotential of storage battery; And DC/DC variable-voltage power supply 3, comprise power transformer and go up electric capacity, the diode that connects, be a stable DC voltage with the low level power supply transformation of importing, as the input power supply of other parts of circuit and the input power supply of charging circuit.In the present embodiment, the current potential rating unit is made up of 1 potential comparator U1 and 4 resistance R 1～R4.Wherein R3, R4 form the reference arm of current potential comparison circuit, and Vcc is from the Vout of power supply transformation part.R1, R2 form cell potential input arm.When charging was carried out, 7 pin of U1 were low levels, and when Vbatt＞Vmax, the 5 pin current potentials of U1 are higher than 6 pin, and high level of 7 pin output of U1 is kept 5 pin current potentials and is higher than 6 pin, and the charging control section branch stops Vbatt being charged.Along with the storage battery electricity consumption, Vbatt descends, and up to Vbatt＜Vmin, the 5 pin level of U1 are lower than 6 pin level, and low level of 7 pin output of U1 is kept 5 pin level and is lower than 6 pin, and charging control circuit charges to battery.Charging control section is divided and is made up of 3 triode Q1～Q3 and 5 resistance R 5～R9.When 7 pin of U1 are exported 1 high level, the Q1 conducting, the base stage low level of Q2, the Q2 open circuit, the base stage high level of Q3, the Q3 open circuit, R9 does not have electric current to pass through, and Vbatt does not charge.When the 7 pin low levels of U1, the Q1 open circuit, Q2 base stage high level, the Q2 path, the base stage low level of Q3, Q3 path, R9 have electric current to pass through, the Vbatt charging.Power supply transformation part main body is a DC/DC power supply changeover device, and after power-generating chip produced electromotive force, to capacitor C 1 charging, the CE utmost point level of power transformer U2 raise through diode D1, and U2 is started.Behind level of 5 pin input of U2, constant voltage vcc of 2 pin output, as the power supply of other parts of circuit, and as the power supply that charges.After the power-generating chip cooling, the power-generating chip current potential disappears, and under the effect of diode, battery can back discharge.By changing the value of R3, R4, can adjust the reference level at the 6 pin places of U1.By adjusting the value of R1 and R2, can realize different Vmax and Vmin.
