How to improve the efficiency and maintenance of battery inverter circuits?

  In order to prevent the early days of the lamp, the following technical measures are used in this circuit: At the center of the transformer primary winding, the constant current inductance L1 is inserted to keep the current flowing through each cycle not mutation, effectively suppressing the overshoot current in the inverter circuit, and the lamp is reduced to the lamp. The transient pretension of the transients. Forklift battery   The parallel capacitance C3 on the transformer primary winding is composed in parallel harmonic grooves, effectively absorb the spike voltage on the primary winding, and the lamp is prevented from excessive excessive consumption of the electrode material.   Increasing the cathode heating winding NK, improves the starting characteristics of low temperature and low voltage, and also reduces the fire voltage required for the lamp tube.   In order to improve the efficiency of the inverter circuit, the ratio of the transformer magnetization current IM and the collector load current IR should be small, however, reducing the magnetization current of the transformer requires a higher amount of inductance of the primary winding, which will increase the volume of the transformer.   Therefore, the efficiency of the inverter circuitry and the volume of the transformer must be appropriately balance the volume of the inverter circuit. The magnetization current IM is usually controlled about 15% of the load current IR.   It is difficult to accurately select the HS value when designing, because the HS value is related to the nature of the magnetic material, and is related to the method of the core assembly. It is best to measure the HS value with the method of experiment, and then determine the HS value of this material according to the efficiency of the inverter circuit.   To repeatedly measure a few times and strive to achieve the best value. The turns Nb of the feedback windings is given in the following formula: NB = NPUBUI, UB is the voltage on the required base windings, in the calculation, set the UB = 114V, then according to the temperature rise of the power tube, Make appropriate corrections, so that Q1, Q2 is lowered. The value of the UB is not the same for different transistors.   The basic principle of selecting the transistor selection transistor is that the switch speed is fast, the saturated pressure drop is small, and the collector current is large.   In addition, the power capacity and withstand voltage requirements of the power transistor are also important. The maximum current ICM3ICPK transistor of the C-E junction of the transistor The rated power consumption of the maximum current ICM3IPK transistor of the ICM3IPK transistor is in addition to the requirements of the power transistor, and another important indicator is the second breakdown tolerance.   In particular, the power transistor that is turned off under reverse bias is more likely to be harmful to the secondary breakdown, and must be paid attention to.
