技术领域 FIELD

[0001] 本发明有关一种升降压转换器,尤指一种充电装置的整合式升降压转换器。 [0001] The present invention relates to a down converter, especially integrated down converter of a charging apparatus.

背景技术 Background technique

[0002] 现今,行动载具发展已朝向无污染、高效能的电动驱动时代。 [0002] Today, mobile vehicle development has been towards non-polluting, energy efficient electric drive era. 然而作为电动驱动的能源必须藉由电池以作为能源储存的容器,使得能源能被储存到电池中。 However, the electric energy must be driven by a battery as the energy storage container, so that energy can be stored in the battery. 通过将能源,例如火力、水力、风力、热能、太阳能以及核能…等转换成电能后,才能够将电能做适当地转换后储存在电池中。 After the energy by, for example, after the fire, water, wind, geothermal, solar and nuclear energy into electrical energy ... etc., it is possible to properly do the electrical converter is stored in the battery. 然而,在电能转换的过程,必须考虑到安全性、高效能以及便利性等问题。 However, the energy conversion process, must take into account security, high performance and convenience issues.

[0003] 请参见图I为现有具有DC/DC转换器的充电装置的电路方块图。 [0003] Referring to FIG. I is a circuit block diagram of a conventional charging apparatus having a DC / DC converter. 如图所示,该充电装置IOA应用于一行动载具(未图示)。 As shown, the charging device is applied to a mobile carrier IOA (not shown). 该行动载具的充电系统主要包含该充电装置IOA与一充电电池20A。 The action of the vehicle charging system including the charging device mainly IOA with a rechargeable battery 20A. 该行动载具可为一电动汽车或一电动机车,并且,该充电电池20A为该电动汽车或该电动机车的车用充电电池。 The carrier may be a mobile electric automobile or a motor car, and, the rechargeable battery for the electric vehicle 20A of the motor vehicle or car battery.

[0004] 该充电装置IOA包含一电磁干扰滤波器102A、一功率因子校正器104A以及一DC/DC转换器106A。 [0004] The charging means comprises an electromagnetic interference filter IOA 102A, a power factor corrector 104A and a DC / DC converter 106A. 该充电装置IOA的该电磁干扰滤波器102A电性连接一外部交流电源Vs,以消除该交流电源Vs的噪声,并防止传导性电磁噪声的干扰。 The electromagnetic interference filter 102A is electrically connected to the charging means IOA an external AC power source Vs, the AC power supply Vs to eliminate noise, and to prevent interference conductive electromagnetic noise. 该功率因子校正器104A电性连接该电磁干扰滤波器102A,以改善转换后的直流电源的功率因子。 The power factor corrector 104A is electrically connected to the electromagnetic interference filter 102A, in order to improve the power factor DC power conversion. 该DC/DC转换器106A电性连接该功率因子校正器104A,以提供不同充电直流电压电平的转换。 The DC / DC converter 106A is electrically connected to the power factor corrector 104A, to provide a different DC voltage level of the charge conversion.

[0005] 当该充电电池20A在使用过程中需要充电的情况下,由于外部所提供的该交流电源Vs的电压电平不见得配合该充电电池20A的电池电压,并且,当该充电电池20A在充电过程中,该充电电池20A的电池电压为动态变化,因此,所采用的该DC/DC转换器106A通常设计为具有一升压式转换器(boost converter),再串联一降压式转换器(buckconverter)的两级式架构,以因应当充电电压高于或低于该充电电池20A的电池电压时的充电需求。 [0005] In the case where the rechargeable battery 20A in the course of charging is required, since the voltage level of the AC power source Vs is supplied from the outside is not necessarily with the voltage of the rechargeable battery cell 20A, and, when the rechargeable battery at 20A during charging, the charging voltage of the battery cell 20A for dynamic changes, therefore, the DC / DC converter 106A employed is generally designed to have a step-up converter (boost converter), and then a series buck converter (buckconverter) architecture of the two, due to the charging voltage should be higher or lower than the charging requirements of the battery voltage when the charging of the battery 20A. 请参见图2为现有两级式DC/DC转换器的电路图。 See Figure 2 is a circuit diagram of a conventional two-stage DC / DC converter. 该两级式DC/DC转换器106A包含一升压式转换器1062A与一降压式转换器1064A。 The two-stage DC / DC converter 106A comprises a boost converter 1062A and a buck converter 1064A. 其中该升压式转换器1062A用以将较低电平的输入电压转换成较高电平的输出电压;同理,该降压式转换器1064A用以将较高电平的输入电压转换成较低电平的输出电压。 Wherein the boost converter 1062A for converting the output voltage into a higher level than the low level input voltage; Similarly, the buck converter 1064A to the higher level of the input voltage into relatively low level output voltage. 在此实施例中,该功率因子校正器104A的输出电压为该两级式DC/DC转换器106A的输入电压Vin。 In this embodiment, the power factor corrector 104A for the output voltage of the two-stage DC / DC converter of the input voltage Vin 106A. 并且,该两级式DC/DC转换器106A的该升压式转换器1062A或该降压式转换器1064A的操作,根据该输入电压Vin与该充电电池20A的电池电压Vb大小。 And, the two-stage DC / DC converter 106A of the boost converter operating 1062A or 1064A of the buck converter according to the input voltage Vin and the voltage Vb of the rechargeable battery cell 20A is the size. 亦即,当该输入电压Vin高于该充电电池20A的电池电压Vb时,该两级式DC/DC转换器106A的该降压式转换器1064A动作,以将较高电平的输入电压Vin转换成较低电平的输出电压Vout以提供该充电电池20A正常充电时所需的充电电压电平。 That is, when the input voltage Vin is higher than the battery voltage Vb 20A rechargeable battery when the two-stage DC / DC converter 106A to 1064A of the buck converter operation, the higher level to the input voltage Vin converted into a lower level of output voltage Vout to provide the required level of charging voltage of the rechargeable battery when the normal charging 20A. 反之,当该输入电压Vin低于该充电电池20A的电池电压Vb时,该两级式DC/DC转换器106A的该升压式转换器1062A动作,以将较低电平的输入电压Vin转换成较高电平的输出电压Vout以提供该充电电池20A正常充电时所需的充电电压电平。 Conversely, when the input voltage Vin is lower than the battery voltage Vb 20A rechargeable battery when the two-stage DC / DC converter 106A to the operation of boost converter 1062A to the lower level of the input voltage Vin into charging voltage level to a higher level to provide an output voltage Vout of the rechargeable battery 20A required for normal charging. 惟,该两级式DC/DC转换器106A由于同时具有升压式转换器与降压式转换器的电路架构,因此,所需的电路元件多,导致增加电路元件使用与维护成本。 However, the two-stage DC / DC converter circuit structure 106A also has since boost converter and buck converter, and therefore, the required plurality of circuit elements, resulting in increased maintenance costs and the use of the circuit elements. [0006] 现有的升降压式转换器(buck-boost converter)可被设计出用以提供输出电压可以高于或低于输入电压的电压电平之用。 [0006] The conventional step-down converter (buck-boost converter) may be designed to provide the voltage level of the output voltage can be higher or lower than the input voltage with. 该升降压式转换器(buck-boost converter)提供电压电平转换时,该升降压式转换器的开关则为同时切换操作,导致整体的切换损失提高,使得电力转换效率大大地降低,所以一般用于低输出功率的时机。 When the buck-boost converter (buck-boost converter) to provide a voltage level converter, the buck converter switching operation was simultaneously switched, resulting in an overall increase of the switching loss, so that the power conversion efficiency is greatly reduced, it is generally used for the timing of low output power.

[0007] 因此,如何设计出一种充电装置的整合式升降压转换器,能以准确地提供该充电电池正常充电时所需的充电电压电平,有效地降低整体的切换损失,使得电力转换效率大大地提升,乃为本案发明人所欲行克服并加以解决的一大课题。 [0007] Therefore, design of integrated down converter A charging device capable of providing a charging voltage level required for normal charging of the rechargeable battery accurately, effectively reducing the overall switching losses, so that the power conversion efficiency is greatly improved, is the desired line to be overcome and resolved a major issue for people in this case the invention.

[0051] 至于该充电装置的整合式升降压转换器10更详细的操作说明,请参见后文。 [0051] 10 For a more detailed description of the operation of down converter integrated charging device, see hereinafter. 当该输入电压Vin高于该充电电池20的电池电压Vb时,该整合式升降压转换器10的该第一开关102为切换操作状态而该第二开关104为全截止操作状态。 When the input voltage Vin is higher than the battery voltage of the rechargeable battery when Vb 20, the integrated step-down converter 10, the first switch 102 to switch the operating state and the second switch 104 is fully OFF operating state. 如此,在此降压操作状态下,该整合式升降压转换器10的电路架构可等效图4A所示的电路架构。 Thus, in this state of the step-down operation, the step-down converter integrated circuit structure 10 may be an equivalent circuit structure shown in FIG. 4A. 请参见图4A为该整合式升降压转换器于高电压差的降压操作的电路图。 See Figure 4A for the down converter circuit diagram of an integrated high voltage difference in step-down operation. 并且,藉由通过控制该第一开关102的切换责任周期(duty cycle)以降低该整合式升降压转换器10的输出电压Vout,以提供该充电电池20正常充电时所需的充电电压电平。 Further, by controlling the first switch through the duty cycle (duty cycle) 102 to reduce the integrated output voltage Vout down converter 10 to provide a charging voltage required for normal charging of the rechargeable battery 20 level. 其中,该第一开关102的切换责任周期通过一脉波宽度调变技术(pulse width modulation,PWM)所控制。 Wherein the duty cycle of the first switch 102 is switched by a pulse width modulation technology (pulse width modulation, PWM) controlled. 也就是说,当该充电电池20在使用过程中需要充电的情况下,外部所提供的交流电源经过电磁干扰滤波器(未图示)滤除交流电源的高频噪声,再通过功率因子校正单元(未图标)转换该滤波后的交流电源为一直流电压(即为该整合式升降压转换器10的输入电压Vin),若该输入电压Vin高于该充电电池20的电池电压Vb时,该整合式升降压转换器10则藉由该第一开关102与该第二开关104的控制,调整为降压操作状态,使得该整合式升降压转换器10的输出电压Vout降低,能以配合该充电电池20的电池电压Vb大小,提供该充电电池20所需的充电电压电平,而避免因充电电压过高导致过度充电使得该充电电池20受到严重破坏,甚至爆炸。 That is, in the case where the rechargeable battery 20 needs to be charged during use, the external AC power supplied through the electromagnetic interference filter (not shown) to filter out high frequency noise AC power supply through the power factor correction unit (not shown) after converting the filtered AC current voltage (that is, the integrated down converter input voltage Vin is 10), if the input voltage Vin is higher than the battery voltage Vb 20 rechargeable battery, and the integrated buck-boost converter 10 by controlling the first switch 102 and the second switch 104 is adjusted to the step-down operation state, so that the integrated buck-boost converter output voltage Vout drops 10 can to fit the size of the voltage Vb of the rechargeable battery cell 20, there is provided a charging voltage level required for the rechargeable battery 20, and to avoid excessive charging caused by excessive charging voltage so that the rechargeable battery 20 has been severely damaged or even explode. 其中,前述的该高电压差在此实施例指该整合式升降压转换器10的输入电压Vin高于该充电电池20的电池电压Vb具有一定的程度。 Wherein the aforementioned high voltage difference in this embodiment means that the integrated buck-boost converter input voltage Vin 10 is above the battery voltage of the rechargeable battery 20 has a certain degree of Vb.

[0052] 此外,当该输入电压Vin低于该充电电池20的电池电压Vb,该第一开关102为全导通或操作在最大切换责任周期的状态而该第二开关104为切换操作状态。 [0052] Further, when the input voltage Vin is lower than the battery voltage of the rechargeable battery Vb 20, the first switch 102 is operating in a full-on state or a maximum duty cycle of the switch and the second switch 104 to switch the operating state. 如此,在此升压操作状态下,该整合式升降压转换器10的电路架构可等效图4B所示的电路架构。 Thus, in this state of the boosting operation, the step-down converter integrated circuit structure 10 may be an equivalent circuit structure shown in FIG 4B. 请参见图4B为该整合式升降压转换器于高电压差的升压操作的电路图。 See Figure 4B for the circuit diagram of a down converter integrated high voltage difference boosting operation. 并且,藉由通过控制该第二开关104的切换责任周期(duty cycle)以提高该整合式升降压转换器10的输出电压Vout,以提供该充电电池20正常充电时所需的充电电压电平。 Further, by controlling the switching duty cycle by the second switch 104 (duty cycle) to increase the output voltage Vout of the integrated down converter 10 to provide a charging voltage required for normal charging of the rechargeable battery 20 level. 其中,该第二开关104的切换责任周期通过一脉波宽度调变技术(pulse width modulation,PWM)所控制。 Wherein the duty cycle of the second switching switch 104 a pulse width modulation technology (pulse width modulation, PWM) controlled by. 也就是说,当该充电电池20在使用过程中需要充电的情况下,外部所提供的交流电源经过电磁干扰滤波器(未图示)滤除交流电源的高频噪声,再通过功率因子校正单元(未图标)转换该滤波后的交流电源为一直流电压(即为该整合式升降压转换器10的输入电压Vin),若该输入电压Vin低于该充电电池20的电池电压Vb,该整合式升降压转换器10则藉由该第一开关102与该第二开关104的控制,调整为升压操作状态,使得该整合式升降压转换器10的输出电压Vout提高,能以配合该充电电池20的电池电压Vb大小,提供该充电电池20所需的充电电压电平。 That is, in the case where the rechargeable battery 20 needs to be charged during use, the external AC power supplied through the electromagnetic interference filter (not shown) to filter out high frequency noise AC power supply through the power factor correction unit (not shown) after converting the filtered AC current voltage (that is, the integrated down converter input voltage Vin is 10), if the input voltage Vin is lower than the battery voltage Vb 20 rechargeable battery, which integrated down converter 10 by controlling the first switch 102 and second switch 104 is adjusted to boost the operating state, so that the integrated down converter output voltage Vout is increased by 10, capable of with the magnitude of the battery voltage Vb of the rechargeable battery 20, to provide a charging voltage level of the rechargeable battery 20 required. 其中,前述的该高电压差在此实施例指该整合式升降压转换器10的输入电压Vin低于该充电电池20的电池电压Vb具有一定的程度。 Wherein the aforementioned high voltage difference in this embodiment means that the integrated buck-boost converter input voltage Vin 10 is lower than the battery voltage of the rechargeable battery 20 has a certain degree of Vb.

[0053] 综上所述可知,无论该整合式升降压转换器10的输入电压Vin高于或低于该充电电池20的电池电压Vb,该整合式升降压转换器10的该第一开关102或该第二开关104可通过适当的切换控制,提供降压操作或升压操作(视该输入电压Vin与该电池电压Vb的关系)。 [0053] In summary seen, regardless of whether the input voltage Vin is integrated down converter 10 is higher or lower than the battery voltage Vb 20 rechargeable battery, which is integrated down converter 10 of the first switch 102 or the second switch 104 may be controlled by a suitable switch, the step-down operation or boosting operation (depending on the input voltage Vin and the relationship between the battery voltage Vb). 因此,在任一种操作状态下(降压操作或升压操作),仅存在有该第一开关102或该第二开关104为切换操作状态,亦即,当降压操作时,该第一开关102为切换操作状态(而该第二开关104为全截止操作状态);当升压操作时,该第二开关104为切换操作状态(而该第一开关102为全导通或操作在最大切换责任周期的状态)。 Thus, in either operation state (step-down operation or boosting operation), or there exists only the second switch 104 to switch the operating state, i.e., when the step-down operation, the first switch of the first switch 102 102 to switch the operating state (switch 104 and the second operating state to the full oFF); when the boosting operation, the second switch 104 to switch the operating state (and the first switch 102 is a full-on or switching operation at the maximum state liability period). 故此,有别于现有技述所采用的升降压式转换器(buck-boost converter)为多个开关同时切换操作。 Therefore, buck-boost converter (buck-boost converter) is different from the prior art used in said plurality of operation switch are simultaneously switched. 因此,本发明所提供的该整合式升降压转换器10则有效地降低整体的切换损失,使得电力转换效率大大地提升。 Accordingly, the present invention provides the integrated buck-boost converter 10 effectively reduce overall switching losses, so that the power conversion efficiency is greatly enhanced.

[0054] 值得一提,当该充电电池20在使用过程中需要充电的情况下,当该整合式升降压转换器10的输入电压Vin接近该充电电池20的电池电压Vb时,例如该输入电压Vin所含的涟波成份而造成该整合式升降压转换器10提供该充电电池20的充电电压有时略高于该电池电压Vb,有时略低于该电池电压Vb的不稳定状态。 [0054] It is worth mentioning that, in the case where the rechargeable battery 20 to be charged during use, when the input voltage Vin is integrated down converter 10 is close to the rechargeable battery 20 when the battery voltage Vb, the input e.g. Vin voltage ripple component contained in the resulting integrated down converter 10 supplies the charging voltage of the rechargeable battery 20 is sometimes slightly higher than the battery voltage Vb, sometimes slightly lower than the unstable state of the battery voltage Vb. 在此操作状态下,无法单独仅使用一降压式转换器或升压式转换器提供反馈控制以输出该充电电池20的电池电压Vb所需的充电电压电平。 In this operating state, not only the use of a separate buck converter or a boost converter provides a feedback control to output a required level of charging voltage of the rechargeable battery in the battery voltage Vb 20.

[0055] 故此,本发明所提供的该整合式升降压转换器10则采用三种操作模式来简化现有的两级式DC/DC转换器架构与克服上述因充电电压不稳定的充电操作。 [0055] Therefore, the present invention provides the integrated buck-boost converter 10 uses three modes of operation to simplify the conventional two-stage DC / DC converter architecture overcomes the above by charging with a charging voltage unstable operation . 第一种操作模式请参见图4C为该整合式升降压转换器操作于低电压差的第一实施例的电路图。 First mode of operation see Fig. 4C integrated buck-boost converter is operated in a circuit diagram of a low voltage difference for the first embodiment. 当该输入电压Vin接近于该充电电池20的电池电压Vb时,亦即输入电压Vin与电池电压Vb两个电压差的绝对值不大时,该整合式升降压转换器10的该第一开关102为可通过一脉波宽度调变技术(pulse width modulation, P WM)所控制其切换责任周期(duty cycle),而该第二开关104则为固定责任周期(fixed duty cycle)的控制,如此,可通过对该第一开关102提供反馈控制,使该整合式升降压转换器10的输出电压Vout能准确地提供该充电电池20正常充电时所需的充电电压电平。 When the input voltage Vin is closer to the rechargeable battery 20 is the battery voltage Vb, battery voltage Vb voltage Vin and the voltage difference between two absolute value that is not input, the integrated step-down converter 10 of the first by switch 102 to a pulse width modulation technology (pulse width modulation, P WM) which is controlled by the switching duty cycle (duty cycle), while the second switch 104, compared with a fixed duty cycle (fixed duty cycle) control, thus, the feedback control may be provided a first switch 102, so that the integrated output voltage of the down converter 10 to provide a charging voltage Vout of the level required for normal charging of the rechargeable battery 20 accurately. 其中,上述的该低电压差的数值范围则视该充电电池20在实际充电应用状况下的设定。 Wherein the difference between the low voltage depends on the numerical range of the rechargeable battery 20 is set in the application status of the actual charge.
