Description

Multichannel power control device and battery electrode drying system equipped with the same

[0001] The present invention relates to a multi-channel power control device and a battery electrode drying system equipped with the same. Specifically, the invention relates to a multi-channel power control device and a battery electrode drying system equipped with the same that can be utilized in various fields using light sources such as xenon flash lamps (Xe flash lamps), such as battery electrode drying, medical equipment, and precision optical equipment, and has a gradual and stable output, allows for efficient power management by dispersing energy, prevents overheating by dispersing heat, improves durability by discharging each channel independently, has a stable output without discharge interference, and has a long lifespan.

[0002] Recently, light sources such as xenon flash lamps are being utilized in various fields, including battery electrode drying, medical equipment, and precision optical equipment. These light sources irradiate flash light through the discharge of a power control device, such as a pulse power supply.

[0003] FIG. 9 is a graph showing the relationship between time and output of a discharge section of a power control device according to the prior art, and FIG. 10 is a photograph of a battery electrode dried by a battery electrode drying system equipped with a power control device according to the prior art.

[0004] Referring to FIG. 9, the discharge portions of all channels of a power control device according to the prior art discharge simultaneously. Accordingly, high energy is consumed because high light energy is generated simultaneously, and there is a risk of overheating due to heat concentration. In addition, there are problems such as the lamp's lifespan being shortened due to excessive discharge, unstable output due to potential discharge interference, and a short equipment lifespan. As can be seen from FIG. 10, the battery electrode dried by a battery electrode drying system equipped with a power control device according to the prior art has a problem in that the drying state of the electrode slurry is poor.

[0005] Patent Document 1 (Korean Registered Patent Publication No. 10-2410532), which is prior art regarding a modular pulse power supply, is disclosed. The modular pulse power supply according to Patent Document 1 allows for easy increase or decrease in output through the addition and removal of pulse modules. However, assuming that the modular pulse power supply of Patent Document 1 discharges sequentially across multiple channels, discharge interference occurs for each channel, causing the output to fluctuate. Furthermore, a time delay problem arises where discharge does not occur at precise intervals for each channel. Therefore, it cannot be utilized in fields where precise discharge control is required, such as battery electrode drying systems.

[0006] Patent Document 2 (Korean Registered Patent Publication No. 10-2388446), which is a prior art regarding a battery electrode sheet drying device and a battery electrode sheet drying method, is disclosed. The battery electrode sheet drying device according to Patent Document 2 dries battery electrodes using an infrared lamp unit in which each set is equipped with a plurality of channel lamps. However, since the discharge portions of all channels discharging in the plurality of channel lamps of Patent Document 2 discharge simultaneously, high light energy is generated simultaneously, resulting in high energy consumption and a risk of overheating due to the concentration of thermal energy. In addition, there are problems such as a shortened lamp life due to excessive discharge, unstable output due to potential discharge interference between multiple channels, and a short equipment lifespan.

[0040] Referring to FIGS. 1 to 4, a multi-channel power control device (100) according to one embodiment of the present invention is described as follows.

[0041] A multi-channel power control device (100) includes a light source (10), a plurality of channel discharge units (20a to 20n), and a control unit (30).

[0042] The light source (10) includes a plurality of channel lamp units (CLa to CLn). Referring to FIG. 2, each of the plurality of channel lamp units (CLa to CLn) may include one or more broadband lamps (XL1, XL2).

[0043] The light source (10) may be a broadband light source that irradiates light having multiple wavelengths of a broadband wavelength band. The broadband wavelength band may have a range from the ultraviolet wavelength band to the near-infrared wavelength band. For example, the range of the broadband wavelength band may be 300 nm to 1200 nm.

[0044] A broadband light source may include at least one inert gas selected from Xe, Kr, Ar, Ne, and He. For example, a xenon lamp containing Xe gas may be used as a broadband light source.

[0045] A plurality of channel discharge units (20a to 20n) are components that perform discharge on each of a plurality of channel lamp units (CLa to CLn). Each of the plurality of channel discharge units (20a to 20n) corresponds to a plurality of channel lamp units (CLa to CLn). For example, assuming there are N channels, the first channel discharge unit (20a) corresponds to the first channel lamp unit (CLa), the second channel discharge unit (20b) corresponds to the second channel lamp unit (CLb), the i-th channel discharge unit (i is a natural number less than or equal to N; not shown) corresponds to the i-th channel lamp unit (not shown), and the N-th channel discharge unit (20n) corresponds to the N-th channel lamp unit (CLn).

[0046] Each of the multiple channel discharge units (20a to 20n) includes a power supply unit (PO). Additionally, each of the multiple channel discharge units (20a to 20n) may further include an igniter (IG), a simmer (SI), and a pulse switch (PS). Additionally, each of the multiple channel discharge units (20a to 20n) may further include a magnetic contactor (MC). Additionally, each of the multiple channel discharge units (20a to 20n) may further include a charge bank (CB).

[0047] The power supply unit (PO) is a component that supplies power to enable the channel discharge units (20a to 20n) to perform discharge. The power supply unit (PO) can supply power to the charge bank (CB). In this specification, the power supply unit (PO) may also be referred to as a "charge power supply unit" or a "capacitor charger."

[0048] The igniter (IG) can apply an ignition voltage to the corresponding channel lamp units (CLa~CLn).

[0049] The Zimmer (SI) can output Zimmer voltage.

[0050] The pulse switch (PS) can discharge a pulse having a peak voltage higher than the zimmer voltage. Referring to FIG. 3, the "peak voltage of the pulse discharged by the pulse switch (PS)" may also be referred to as the "output voltage of the pulse switch (PS)". In this specification, the pulse switch (PS) may also be referred to as a "lamp discharge unit".

[0051] The electronic contactor (MC) can selectively apply one of the ignition voltage and a combination of zimmer voltage and pulse to the corresponding channel lamp units (CLa~CLn). For example, the "combination of zimmer voltage and pulse" for each channel can be represented in the form of the graph for the first channel (1ch), the graph for the second channel (2ch), and the graph for the Nth channel (Nch) in FIG. 4 (discharge operation). For example, the "combination of zimmer voltage and pulse" for all channels can be represented in the form of FIG. 3.

[0052] For example, the electronic contactor (MC) may be a switch that switches between an on state and an off state. For example, when the electronic contactor (MC) is in one of the on state and off state, the electronic contactor (MC) may apply an ignition voltage to the corresponding channel lamp units (CLa~CLn), and when the electronic contactor (MC) is in the other of the on state and off state, the electronic contactor (MC) may apply a combination of Zimmer voltage and pulse to the corresponding channel lamp units (CLa~CLn).

[0053] The charging bank (CB) can be charged by power supplied from the power supply unit (PO) and discharged by the pulse switch (PS). In this specification, the charging bank (CB) may also be referred to as a "capacitor bank."

[0054] The control unit (30) controls the plurality of channel discharge units (20a~20n) so that the plurality of channel discharge units (20a~20n) sequentially discharge to the corresponding channel lamp (CLa~CLn) among the plurality of channel lamps (CLa~CLn).

[0055] For example, referring to FIG. 1 and FIG. 3, there are N channel discharge units (20a to 20n) and N channel lamps (CLa to CLn), and if the cycle time for the discharge of the entire first channel discharge unit (20a) to the Nth channel discharge unit (20n) is T [sec], the control unit (30) can control the multiple channel discharge units (20a to 20n) so that the multiple channel discharge units (20a to 20n) discharge sequentially at a frequency of N / T [Hz].

[0056] For example, the control unit (30) can control the electronic contactor (MC) so that the electronic contactor (MC) applies an ignition voltage to the corresponding channel lamp units (CLa~CLn). When the channel lamp units (CLa~CLn) are lit up upon the application of the ignition voltage, the control unit (30) can control the electronic contactor (MC) so that the electronic contactor (MC) applies a combination of a zimmer voltage and a pulse to the corresponding channel lamp units (CLa~CLn). Upon the application of this combination of zimmer voltage and pulse, the light source (10) can be operated in such a way that a plurality of channel lamp units (CLa~CLn) sequentially irradiate flash light.

[0057] For example, referring to FIGS. 1 and FIGS. 3, a plurality of channel discharge units (20a to 20n) are composed of a first channel discharge unit (20a) to an Nth channel discharge unit (20n), and if the cycle time for the discharge of the entire first channel discharge unit (20a) to the Nth channel discharge unit (20n) is T [sec], the control unit (30) can control the plurality of channel discharge units (20a to 20n) such that the time interval between the pulse discharge of the i-th channel discharge unit (i is a natural number from 1 to N-1) and the pulse discharge of the i+1-th channel discharge unit is T / N [sec].

[0058] For example, the control unit (30) can control one or more of the power supply unit (PO), the charging bank (CB), and the pulse switch (PS) so that the time interval between the pulse discharge of the i-th channel discharge unit and the pulse discharge of the i+1-th channel discharge unit is T / N [sec].

[0059] According to the first feature of an embodiment of the present invention, a multi-channel power control device (100) comprises: a light source (10) having a plurality of channel lamp units (CLa~CLn); a plurality of channel discharge units (20a~20n) each having a power supply unit (PO) and performing discharge on each of the plurality of channel lamp units (CLa~CLn)—wherein each of the plurality of channel discharge units (20a~20n) corresponds to the plurality of channel lamp units (CLa~CLn); and a control unit (30) for controlling the plurality of channel discharge units (20a~20n) so that the plurality of channel discharge units (20a~20n) sequentially discharge to the corresponding channel lamp unit (CLa~CLn) among the plurality of channel lamp units (CLa~CLn).

[0060] Accordingly, the output is gradual and stable, and efficient power management is possible by dispersing energy, and overheating can be prevented by heat dissipation. In addition, each channel discharges independently to improve durability, and the output is stable without discharge interference, and the lifespan is long. Furthermore, by maintaining an accurate discharge interval, it can be applied to a battery electrode drying system (1000), and in the event of a malfunction, only the relevant module can be quickly replaced, thereby improving equipment productivity and reducing maintenance costs.

[0075] For example, the control unit (30) can control one or more of the power supply unit (PO'), the charging bank (CB), and the pulse switch (PS) so that the time interval between the pulse discharge of the i-th channel discharge unit and the pulse discharge of the i+1-th channel discharge unit is T / N [sec].
