Description

Energy processing system and method

Technical field

The present disclosure relates to the field of communications technologies, and in particular, to an energy processing system and method.

Background technique

In the communication device, the system device is powered by a DC power supply, and the DC power supply is turned off and on, and a metal oxide semiconductor field effect transistor MOSFET (MOS) is generally used. Since the DC power supply must implement anti-reverse connection, the MOS tube must implement anti-reverse function. In addition, the DC power supply is generally externally connected to the capacitor, so the MOS tube should be slowly started. The MOS tube slowly turns on the MOS tube to slowly charge the capacitor by slow start, so that the MOS can be reliably turned on.

When lightning strikes in the natural world, the lightning surge generated by lightning strikes or lightning strikes will be directly applied to the anti-reverse and slow-start MOS tubes on the DC power supply. The energy generated by the lightning surge is large, and the excessive lightning surge energy will be damaged. MOS tube, therefore, the DC power supply must be protected from lightning surge to protect the anti-reverse MOS tube from damage.

There are two common schemes for protecting the anti-reverse MOS tube from damage:

Solution 1: DC power supply input terminal plus single-level protection and MOS plus protection scheme, Figure 1 is a circuit diagram of the DC power supply input terminal plus single-stage protection and MOS plus protection scheme in the related art, as shown in Figure 1, The plan is:

When a lightning surge is added to the DC power supply, the lightning surge energy is high, the peak voltage is high, and the operating voltage of the protective device TVS VD1 and VD2 is exceeded. The TVS VD1 and VD2 clamp the lightning energy to reduce the anti-reverse VT1MOS. Tube, slowly open the peak voltage at both ends of the VT2MOS tube, so that the peak voltage is reduced to the safe working range of the MOS tube. VD1 and VD2 play a protective role in the occurrence of lightning surges, ensuring that the MOS tube works normally when a lightning surge occurs.

The DC input power supply generally has an input range of -36V to -72V. In this range, the DC power supply should work normally. The protection devices VD1 and VD2 cannot operate. Therefore, VD1 and VD2 can only select TVS above 72V. When using a TVS above 72V and a lightning surge in the DC power supply, the TVS clamp voltage is high, and the residual voltage at both ends of the TVS is high, so that the anti-reverse MOS VT1 and VT2 can only select MOS tubes above 200V, and the MOS tubes above 200V are bulky. The internal resistance is large, the heat consumption is high, the pressure is high, and the cost is high.

Solution 2: The DC power supply input terminal is equipped with dual-level protection and MOS plus protection scheme. Figure 2 is a circuit diagram of the DC power supply input terminal plus dual-level protection and MOS plus protection scheme in the related art, as shown in Figure 2, The plan is:

When a lightning surge is applied to the DC power supply, the surge energy is high due to lightning surge, and the peak voltage is high. It exceeds the protection devices TVS VD1 and VD2, and the varistor RV1 operates voltage. VD1, RV1, and VD2 clamp the lightning surge energy. Absorb, reduce the anti-reverse VT1MOS tube, and slowly start the spike voltage at both ends of the VT2MOS tube, so that the peak voltage is reduced to the safe working range of the MOS tube. VD1, RV1, and VD2 play a protective role in the event of a lightning surge, ensuring that the MOS tube operates normally in the event of a lightning surge.

The DC input power supply generally has an input range of -36V to -72V. In this range, the DC power supply should work normally. The protection devices VD1, RV1, and VD2 cannot operate. Therefore, VD1, RV1, and VD2 can only select TVS and voltage sensitivity above 72V. When using TVS with 72V and above and pressure sensitive, DCS power supply power supply lightning surge, TVS and pressure sensitive clamp voltage is high, so that anti-reverse MOS VT1 and VT2 can only select MOS tube above 200V, MOS tube above 200V is large. Large internal resistance, high heat consumption, high pressure resistance and high cost.

Both of the above schemes can only be operated when the lightning surge is greater than 72V, and the residual voltage after the action is high. The anti-reverse MOS tube can only select MOS above 200V. The 200V MOS tube is large in volume, large in internal resistance, high in heat consumption, high in withstand voltage, and high in cost.

In view of the above technical problems in the related art, an effective solution has not yet been proposed.

The first surge protection unit 38 is coupled to the secondary side 364 of the energy transfer unit 36 for consuming lightning surge energy transferred to the secondary side 364.

Through the above system, by transferring the lightning surge energy to the secondary side of the energy transfer unit 36, the energy of the lightning surge to the anti-reverse unit 32 and the slow-start unit 34 is small, thereby reducing the anti-reverse unit 32 and the slow-start unit. The residual voltage of 34 can further solve the problem of high residual voltage of the lightning surge anti-reverse unit and the slow-start unit in the related art.

It should be noted that, when the above system reduces the residual voltage of the anti-reverse unit 32 and the restart unit 34, the withstand voltage can be used in the system compared with the anti-reverse unit and the slow-start unit used in the prior art system. The lower anti-reverse unit and the slow-start unit can solve the problems of large volume, large internal resistance, high heat consumption, high withstand voltage and low cost of the anti-reverse unit and the slow-start unit in the related art.

For a better understanding of the invention, the invention is further explained below in conjunction with the preferred embodiments.

4 is a system for reducing anti-reverse MOS tube lightning surge residual voltage according to a preferred embodiment of the present invention. First, as shown in Figure 4, the system includes the following units:

First-level surge protection unit, second-stage surge protection unit, anti-reverse unit, slow-start unit, energy storage unit, lightning surge energy transfer unit, surge protection unit 1, rectification energy storage unit, surge protection unit 2.

Corresponding to the above-mentioned slow-moving unit 34, the surge protection unit 1, the rectifying energy storage unit and the surge protection unit 2 shown in FIG. 4 correspond to the first surge protection unit 38, and the first-stage wave shown in FIG. The surge protection unit and the second stage surge protection unit are equivalent to the second surge protection unit connected to the primary side 362 of the energy transfer unit 36.

The principle of reducing the anti-reverse MOS tube lightning surge residual voltage of the system shown in FIG. 4 is as follows:

When a lightning surge occurs in the DC power supply, the lightning surge energy acting on the DC power supply is large, and the current flowing through the lightning surge energy transfer unit is also large. The lightning surge energy transfer unit transfers the lightning surge energy. The transferred lightning surge energy is consumed by the surge protection unit 1 on the one hand; on the other hand, the rectified energy storage unit is used to rectify the alternating current into a direct current for the rectified energy storage unit to be stored, and also through the surge protection unit 2 Consume stored energy. The surge protection unit 1, the rectification energy storage unit, and the surge protection unit 2 work together to consume lightning surge energy.

It is possible to select a protection device such as a TVS and a varistor with a lower operating voltage, and a MOS tube with a smaller withstand voltage can be selected, which solves the problems of large volume, large internal resistance, high heat consumption, high withstand voltage and high cost of the current MOS tube.

When a surge current surge occurs in the DC power supply, the lightning protection surge device can consume the lightning surge energy when the lightning surge voltage is small, and the lightning surge flows to the anti-reverse MOS. The energy on the small is small, and the lightning surge energy on the anti-reverse MOS is small, and the anti-reverse MOS can select the MOS tube with lower withstand voltage. Solution 1 Option 2 Due to the high operating voltage of the protection device, only the MOS tube above 200V can be selected. Select a MOS tube with low withstand voltage.

FIG. 5 is a second system for reducing the residual voltage of a lightning surge of a MOS transistor according to a preferred embodiment of the present invention. As shown in FIG. 5, the working principle of the system is as follows:

When a lightning surge occurs in the DC power supply, the lightning surge energy acting on the DC power supply is large, and the current flowing through the current transformer T1 is also large, and the current transformer T1 senses the lightning surge energy to the secondary side. The lightning surge energy induced to the secondary side is consumed by the protection device VD3 on the one hand; on the other hand, the alternating current is rectified into direct current through the rectifier bridge D1, the energy is stored for the capacitor C2, and the stored energy is also consumed by the R7. VD3, C2, and R7 work together to consume lightning surge energy.

It should be noted that the current transformer T1 shown in FIG. 5 corresponds to the lightning surge energy transfer unit shown in FIG. 4, and the protection device VD3 shown in FIG. 5 corresponds to the surge protection unit 1 shown in FIG. The rectifier bridge D1 and the capacitor C2 shown in FIG. 5 correspond to the rectifying energy storage unit shown in FIG. 4 described above, and R7 shown in FIG. 5 corresponds to the surge protection unit 2 shown in FIG.

In the above system, the DC supply current can select a protection device such as a TVS and a varistor with a lower operating voltage, and a lower operating voltage protection device is selected. When a lightning surge occurs in the DC power supply, the system can be used in a lightning strike. When the surge voltage is very small, the protection device can consume the lightning surge energy, so that the energy of the lightning surge to the anti-reverse MOS is small, and the lightning surge energy on the anti-reverse MOS is small, and the anti-reverse MOS can select MOS tube with lower withstand voltage. Solve the problem that the current action voltage of the protection device is high, the anti-reverse MOS tube is large in volume, large in internal resistance, high in heat consumption, high in withstand voltage, and high in cost.

Energy, and the varistor RV2 and the inductor L1 are added to the secondary side of T1, and the VD3 as a whole can be equivalent to the surge protection unit 1 shown in FIG. 4 described above.

As shown in FIG. 7 , the working principle of the system is basically the same as that of the system illustrated in FIG. 5 .

Yes, the guard device VD4 is connected in parallel with the resistor R7 on the secondary side of T1, and R7 as a whole may correspond to the surge protection unit 2 shown in FIG. 4 described above.
