It includes the input AC-DC converter diagram, the charge-circuit diagram; the control circuit diagram; the charging and discharging indicator circuit; the DC-AC converter diagram; the output AC-DC converter diagram; and the converter diagram. The specific explanations of these circuits are given with Figures as follows:
  • Figure 4 is the input AC-DC converter diagram.
  • the input AC-DC converter part of the circuit adopts a new type of switching power supply featuring high efficiency of conversion, stable working condition, wide range of application voltage, and protection of under-voltage.
  • it can substitute the traditional power transformer component which is low in conversion efficiency and working stability, and narrow in the range of application voltage.
  • the 220V AC is commutated by the rectifier bridge A1.
  • the 220V unstable direct voltage was produced after the power factor correction circuit made up of diodes D3, D4 and D5 and capacitances C3 and C4 is filtered;
  • Tube fuse FU is connected in series with the input terminal of the 220V AC for over-current protection;

  • the common mode L1 connected in series with and C1 and C2 connected in parallel with the 220V AC is used to eliminate the mutual interference between AC and post-Circuit; resistances R2 and R3 are the starting-resistor of integrated circuit IC1.
  • the induced voltage on the secondary coil of transformer Ts1 is converted to two groups of DC after commutated by diode D2 and D7 and then filtered by capacitances C8 and C9; one group charges the battery through diode D6; the other is fed to the control circuit with test switch TEST.
  • the voltage induced on the secondary coil of transformer Ts2 is commutated through switching diode D13, filtered through C12 and then is fed on the control terminal C through photoelectric coupler A2; IC2, the voltage reference, tests the output voltage through resistances R11 and R12 to compare with the reference voltage 1.25V; when the direct voltage charging the battery rises, the current of the photoelectric coupler A2 flowed through photodiode increases and intensifies the conduction of the photosensitized receiving device through the photoelectric coupler A2.
  • the output pulse length of IC1 becomes narrowing and is coupled through transformer to the secondary coil Ts1 in order to make the output voltage decrease, and vice versa, namely when the output voltage rises, the pulse length is made to be narrowing though feedback in order to make the output voltage decrease; when the output voltage decreases, the pulse length is made to be widening though feedback in order to make the output voltage rise. All is to guarantee the stabilizing of the output voltage.

  • AC is normal, the test switch is switched on.
  • the emergency luminaire is being charged and the energy of the fluorescent lamp is provided by electronic ballast. Now switch off the test switch. Because AC is still fed to the Input end of the emergency luminaire for energy-saving light, it is still charging.
  • the control circuit switches by reason of the power cut, and thus batteries change the circuit by DC-AC and output AC-DC to form a high voltage direct current which provides the fluorescent lamp with lighting power through electronic ballast.
  • FIG. 5 is the current-limited charging circuit diagram. This circuit is made up of resistance R8 and triode V4. While the battery is being charged, the current flowed through R1 forms a voltage drop on R1. When the current increases and the voltage drop reaches 0.6V as a result, V4 is saturated and conducted, IC2 becomes a short circuit and the current flowed through the photoelectric coupler A1 increases. Then with the help of feedback circuit, the output pulse length of IC1 is made to be narrowing and the output voltage decreases. Sequentially the increase of charge current is curbed.
  • Figure 6 is the control circuit diagram; When AC is normal, the direct voltage on the control circuit is shared by R13 and R17 and is fed on the base of triode V6 in order to make V6 saturated and conducted; then the base voltage of triode V7 is 0V and the voltage connected with the base of triode V7 through resistance R23 does not take effect.

  • This voltage is divided by resistances R14, R25 and resistance R24 in order to maintain the continuous saturation and conduction of triode V7; at the same time, it provides power to DC-AC circuit through diode D14. Adjusting the resistance value of resistances R14, R24 and R25 can force triode V7 to stop working under different voltages in order to achieve the over-discharge protection of the battery as well as to avoid the damage of the battery from over-discharge.
  • Figure 7 is the charging and discharging indicator circuit.
  • the direct voltage formed after commutated through diode D2 and then filtered through capacitance C8 is larger than the breakdown voltage of stable diode D16, so stable diode D16 is conducted; direct voltage is fed on the base of triode V5 with stable diode D16 and current-limiting resistance R15 in order to make triode V5 saturated and conducted.
  • the collector voltage of triode V5 is 0V; light-emitting diode D17-G does not work for short of power, and it shows battery unconnected.
  • the direct voltage formed after commutated through diode D2 and then filtered through capacitance C8 is far less than the breakdown voltage of stable diode D16 so that stable diode D16 is closed.
  • the base of triode V5 is powerless so that Triode V5 is closed.
  • the collector voltage of triode V5 keeps the high level; light-emitting diode D17-G starts to emit light with power, and it shows battery connected; the resistance value of adjusting resistance R15 can change the light brightness of D17-G.
  • the control circuit acts, B2 gets power from relay RYL, and the normal open contact gets power after turning on and is fed on light-emitting diode D17-R through current-limiting resistance R22; light-emitting diode D17-R starts to emit light with power and shows the discharge is in progress.

  • the control circuit acts, relay RYL gets power, the normal open contact is turned on, and the battery gets power from B2 through the normal open contact; diode D14, start resistances R18, R19, R20 and R21 trigger the oscillator to work and drive triodes V1 and V2 is driven to work and conducted alternatively; sinusoidal waveform high-frequency AC is formed at E1 and E2, both ends of the secondary coil of transformer.
  • This circuit can still work continuously when loading changing or even open circuit. Adjusting the resistance value of resistances R18, R19, R20 and R21 as well as the parameter of transformer L5 can change the output voltage and
  • Figure 9 is the input AC-DC converter diagram. It is to convert high-frequency and high-voltage AC into high-voltage DC. When AC is powered off, or the test switch is turned off or the input AC-DC converter in Figure 4 is under-voltage protection action, the control circuit acts.
  • Figure 8 is the output high-frequency and high-voltage AC of DC-AC Converter. It becomes DC after flowing through the bridge rectifier circuit made up of diodes D9, D10, D11 and D12.
  • Capacitance C10 is filtering capacitance. It is used to smooth the ripple of DC.
