Description
Technical Field
The invention relates to the field of low-voltage power supply systems and large dynamic load power supply, in particular to a circuit with a BOOST energy storage circuit matched with dynamic load change.
Background
Under the condition that the number of T/R elements of the transmitter is less, the power is less, and if the T/R elements are far less than the output power of the generator, or the receiving and transmitting work repetition frequency of the transmitter is higher (more than or equal to 5KHz), the influence on the generator is less. However, in the electronic work, the situation that the repetition frequency of the work of the transmitter receiving and transmitting is less than or equal to 5KHz is necessarily met, and the transmitting power is increased along with the requirement of equipment development. When the large dynamic change reaches about 20% of the power of the generator, the generator is greatly affected, the generator is vibrated, modulation is generated, the whole power supply system is affected, and serious consequences are generated.
The current mature scheme is a dummy load scheme, namely when receiving, the dummy load is added to offset load change and reduce the influence of load dynamic change on a power supply system. However, the dummy load scheme generates a large amount of heat, increases heat dissipation cost, and increases system power consumption, and meanwhile, the dummy load is basically fixed and cannot be automatically compensated with load changes (different radio frequency operating frequency bands, the power of the dummy load is greatly changed), so that the power of the dummy load is still increased or decreased after compensation. It follows that the dummy load scheme is very costly but has limited effectiveness.
In some application scenarios, such as future war drones and unmanned vehicles, which are currently the main power generation systems of DC28V and single-phase 220V/50Hz generators, will be in heavy use. The power capacity of the transmitter is generally 5-20 KVA, while the load of the existing transmitter is generally 1-12 KW, which greatly affects the generator in the future. Due to cost performance and capacity factors of platforms such as unmanned aerial vehicles and unmanned vehicles, the critical power matching problem needs to be solved.

Detailed Description
All features disclosed in all embodiments in this specification, or all methods or process steps implicitly disclosed, may be combined and/or expanded, or substituted, in any way, except for mutually exclusive features and/or steps. The technical concept, the technical problems to be solved, the working principle, the working process and the advantages of the present invention will be fully described in detail with reference to the accompanying drawings 1 to 4.
In the process of solving the background technical problem, the invention also finds the following technical problems: the active energy storage module adopts a BUCK energy storage method in some high-voltage occasions, but because the input voltage is lower, the voltage of an energy storage capacitor is very low by adopting the method. In practical application, for a DC28V power supply system, the energy storage capacitor can only reach 16V, and since the stored energy is in direct proportion to the square of the stored voltage, the energy storage is very low, and only a capacitance method can be used; in addition, after the voltage is low, the current is very large, for a 1-2 KW system, the current can reach more than 60-120A, and the line loss is very large; meanwhile, the large current causes large loss of the MOS tube and the freewheeling diode.
Therefore, in the technical concept of the invention, the BOOST conversion is adopted for energy storage and the like to solve the technical problems. In specific application, the design concept is as follows: the BOOST charging of the energy storage capacitor through the BOOST circuit has the advantages that as 3 rd generation semiconductor application develops, the voltage value can be increased, more energy can be stored, and the energy storage voltage value is very suitable for a DC28V power supply system, for example, the voltage value can be set to be about 48V; for the DC270V power supply system, for example, it can be set to about 500V. The scheme can enable the charging energy and power to be set more flexibly, and meanwhile, due to the fact that high voltage works, corresponding working current is small, so that the current of a switching device is reduced, and the efficiency is improved.
In a specific embodiment of the present invention, the specific implementation includes the following processes: by using the current sensor to detect the current of the main circuit, the current at the end time of a dynamic load high power consumption stage (in a transmitter system scene, generally, a transmission T stage) can be detected, and then the BOOST charging circuit starts to charge the energy storage capacitor at the rear end through digital control. In a transmitter system scene, when a power supply system is in a transmitting array R stage, the power supply power of the power supply system basically keeps the original current, and then the charging current is controlled through a system control module according to the difference value of the transmitting power and the receiving power of the system, so that the charging power is gradually reduced. If the receiving time is long (a reference value can be set according to the actual situation), the BOOST circuit is controlled to stop working after the energy storage capacitor is charged fully; if the receiving time is not long, the BOOST circuit is controlled to gradually supply the energy storage capacitor with the energy which can not be fully charged, but the charging and discharging functions of the energy storage capacitor are not influenced, so that the slow power reduction effect of the generator can be still achieved. The invention realizes the controllability of the charging slope through the control of the opening time of the BOOST circuit, thereby enabling the generator at the front end to sufficiently respond to the change of the slow reduction of the power.
Similarly, when the dynamic load consumes a large amount of power (T phase), the energy of the energy storage capacitor is released through the BUCK circuit of the energy storage circuit. In the scenario of a DC28V power supply system, the front-end storage capacitor can only be placed at the bus voltage DC 28V. The transmitter transceiver system detects the current of the power supply system according to the given increased power of the transmitting and receiving power, and if the current is reduced, the current controls the discharge power of the BUCK circuit, so that the power supply of the power supply system also slowly increases the power consumption, and the capability of matching the pulse load in the power supply system is realized.
In the above technical solution, the embodiment of the present invention actually adopts two-stage transformation, which can be performed without mutual influence, and thus has the advantage of flexible adjustment of charging power and discharging power. In the specific implementation process, only 1 path of sensor is needed when the main current is detected, the bus current of the main path can be accurately detected, calculation is not needed, and therefore the reaction is fast and accurate. Meanwhile, the acquired current is used as data of the energy storage circuit, the energy storage and release initial point and the charging and discharging power of the active energy storage module can be controlled by changing the current change of the power supply system, and the method for sharing the power by the bus of the power supply system is not influenced, so that the effect of stabilizing the power supply system is achieved.
In the technical scheme, the current sensor of the main circuit detects the main current and additionally detects the system power, which is beneficial to realizing a systematic intelligent detection function.
In a specific application process, because the load power is different, according to the technical scheme of the embodiment of the invention, a plurality of active energy storage modules can be naturally connected in parallel to match the load size. Because each active energy storage module is independent of a storage capacitor and has respective power current limitation, the aim of natural parallel connection can be fulfilled without adding a special parallel cascade and control circuit. When one active energy storage module is damaged, the active energy storage module can naturally exit without influencing the work of other active energy storage modules and systems. In order to prevent the MOS tube from short circuit, a fuse can be added for protection.
The method provided by the embodiment of the invention is based on BOOST BOOST conversion control, a Buck circuit and the like, improves the active energy storage of the energy storage capacitor, improves the efficiency, realizes the matching of the transmitter when the transmitting power and the receiving power change, and can also be connected with the output side of the power electronic converter.
After the system is started, when the main circuit starts to supply power, the energy storage capacitor C of the active energy storage module is automatically connected with the main circuit charge Charging to the supply voltage (e.g., 28V). The active energy storage module delays 300ms (avoids the impact current of a system, reduces the impact influence of power on a generator) for starting, then performs slow start starting, the slow start time can be set to 300ms, and the active energy storage module is in a standby state after being fully filled with a rated value; the control circuit of the BOOST of the active energy storage module is also in a standby state at this time.
After the system receives and transmits a signal of a receiving and transmitting (T/R) component, the signal is transmitted to a control terminal of an active energy storage module, frequency information (the purpose of the frequency information is different transmitting frequencies, the output power of a transmitter is different, the fluctuation range of the transmitter is more than 20 percent) and the number of working units are simultaneously given, and the information also determines the different transmitting powers of (T/R); meanwhile, the current sensor of the main circuit sends the current information of the main circuit to the control circuit of the BOOST.
When the T/R component is in a transmitting mode, required high power is obtained according to the information, the working output power of a BUCK circuit of the active energy storage module is controlled at the moment, the BUCK circuit sets starting time (about 100 us), and the starting time is short and has no influence on the generator; the voltage of the energy storage capacitor is stabilized after reaching the power supply voltage, and the voltage is stored in the energy storage capacitor C charge The energy is released to a load, the rising rate of the main power current is detected in the energy releasing process (the rising rate mainly determines the response time of the generator and can be adjusted), when the rising rate of the main power current is detected to be too high (a reference value can be set according to the actual condition), the output power of the active energy storage module is increased (in a safe protection interval), otherwise, the rising rate of the main power current is detected to be too low (the reference value can be set according to the actual condition), the output power of the active energy storage module is reduced (can be properly relaxed) until the stored capacitor energy is released and stops working, and if the energy is not released, the working is stoppedAfter all, the whole energy storage is not influenced.
When the working mode of the T/R assembly is switched from the transmitting mode to the receiving mode, the active energy storage module can be synchronously switched to the energy storage working mode. When the T/R component is in a receiving mode, the required power is small, the input power of the active energy storage module is controlled at the moment, and the energy is stored in the energy storage capacitor C charge Detecting the storage capacitor C in the process of storing energy charge When the voltage is overvoltage, the active energy storage module is provided with hiccup protection for ensuring the energy storage capacitor C charge The voltage is maintained in a safe range and can be an energy storage capacitor C s The energy consumption caused by circuit parasitic parameters is supplemented, and when the working mode of the T/R component is switched from the receiving mode to the transmitting mode, the active energy storage module can be synchronously switched to the energy release working mode.
