Detailed Description
The invention is further described with reference to the following description and embodiments in conjunction with the accompanying drawings.
As shown in fig. 1 to 10, a multiport converter circuit adapted to an impulse load includes a super capacitor CS, a solar array SA, a peak tracking system (MPPT)101, a storage battery 104, a storage battery charging regulator 102, a storage battery discharging regulator 103, and a bus, where the solar array SA is connected to the bus through the peak tracking system 101, the storage battery 104 is connected to the bus through the storage Battery Charging Regulator (BCR)102 and the storage Battery Discharging Regulator (BDR)103, respectively, the super capacitor CS is connected to the bus, a bidirectional DC/DC converter 105 is connected between the super capacitor CS and the bus, a PID regulator 107 is connected between the bidirectional DC/DC converter 105 and the bus, and the bus is connected to a load 106.
A control method of a multi-port converter circuit adaptive to a pulse load adopts a control mode of a super capacitor to adjust a bus, and directly uses the voltage at two ends of the super capacitor as a control signal to control the charging and discharging of a battery and the bus. Thus, the BUS (BUS) can respond to the change of the load rapidly.
The solar array is connected with the bus through the MPPT (peak tracking system), and the MPPT controls the solar array SA (solar array) to output energy according to the power requirement of the spacecraft, so that the maximum output power of the solar array can be effectively exerted. The battery terminals are also directly connected to the bus bars. The voltage Vcs across the supercapacitor CS is used as a control signal to divide a control region, so that the battery (i.e., the storage battery 104) enters a BCM (battery charge management) charging region and a BDM (battery discharge management) discharging region, thereby managing the charging and discharging of the battery. The voltage Vcs across the super capacitor is connected with the load 106 through the bidirectional DC/DC converter 105, so that the dynamic response of the bus can be improved.
Selection of the super capacitor CS:
the function of the super capacitor CS is to quickly adjust the transient current load of the response bus. Since the energy stored by the capacitor is proportional to the square of the capacitor voltage, the voltage range of the supercapacitor CS is preferably chosen to be close to the bus voltage, so that the steady state voltage of the supercapacitor is taken to be 95V. Here a 3kw bi-directional DC/DC converter 105 with a super capacitor voltage range of 70-95V and a bus steady state voltage value of 100V.
Calculation of the capacitance value of the supercapacitor CS:
assuming the desired pulsed power supply is VoutPulse current is IpDuration of tpThen the energy required is at least:
Ep＝Vout*Ip*tp
during pulse formation, the voltage at the end of the energy storage capacitor is VcmaxDown to VcminAssuming that the conversion efficiency of the pulse forming topology is τ, the following relationship exists:
obtained from the above formula:
because the pulse power is adjustable, and the pulse amplitude and the pulse duration are adjustable, the selection of the capacitor must be comprehensively considered by considering the maximum pulse energy and the maximum and minimum settings of the capacitor voltage, and the selection is usually larger.
One advantage of the invention is that by utilizing the characteristic that the super capacitor can be charged and discharged in a short time, when the bus has a large transient pulse current load, the voltage ripple caused by the action of the capacitor can be controlled to be small. The voltage Vcs at two ends of the super capacitor is used as a control signal, so that the whole system (namely a satellite power supply system) works in different areas.
a) SUN field 85-95V
As shown in fig. 4, when the voltage value Vcs across the super capacitor is between 85-95V, the system operates in the SUN domain, and at this time, the solar array supplies power to the bus while charging the battery at a constant maximum current.
b) Charging area of 80-95V
As shown in FIG. 5, the system charges the battery linearly when the voltage value Vcs across the super capacitor is 80-85V. The voltage value of each super capacitor corresponds to a battery charging current value. When the system enters the SUN domain, the system maintains a constant current value to charge the battery.
c) Discharge area of 70-80V
As shown in FIG. 6, when the voltage value Vcs of the super capacitor is between 70 and 80, the voltage provided by the solar array to the bus load is not enough to maintain the normal operation of the bus load. At this time, the battery discharge supplies power to the bus, and the solar array and the battery supply power to the bus at the same time.
The Vcs voltage is converted into a control signal after linear conversion through a differential circuit, and then PID control is carried out.
The control flow comprises the following steps:
1) control of the SUN domain:
as shown in fig. 7, Vcs is compared with MPPT, and after a lower value is obtained, PID control is performed as a control signal of the SUN domain by comparing with the bus-side current.
2) And (3) battery charging and discharging management:
as shown in FIG. 8, Vcs is taken high in comparison to the BCM battery management voltage. And comparing with the sample of the inductive current of the battery for PID control.
3) Control of bus voltage:
as shown in fig. 9, the BUS voltage sampling value is compared with the reference value thereof to perform PID control, and the BUS voltage is controlled. Therefore, the super capacitor can rapidly adjust the bus voltage.
As shown in fig. 10, when the bus has a 20A square wave pulse load, the impedance of the bus is maximized when the frequency of the load is increased to 1.4 KHz.
According to the multi-port converter circuit adaptive to the pulse load and the control method thereof, provided by the invention, by utilizing the characteristic that the super capacitor can be charged and discharged in a short time, when a bus has a large transient pulse current load, the voltage ripple caused by the action of the capacitor can be controlled to be very small.
The invention provides a multi-port converter circuit adaptive to a pulse load and a control method thereof, and provides a novel high-power supply controller with high power density, good load dynamic characteristics and low output impedance in order to adapt to second-level or minute-level pulse power loads.
The foregoing is a more detailed description of the invention in connection with specific preferred embodiments and it is not intended that the invention be limited to these specific details. For those skilled in the art to which the invention pertains, several simple deductions or substitutions can be made without departing from the spirit of the invention, and all shall be considered as belonging to the protection scope of the invention.
