Abstract

<P>PROBLEM TO BE SOLVED: To provide a method by which a direct current-alternating current converter or an alternating current-alternating current converter can charge a storage battery without use of a separate dedicated charger while a current is controlled so that a current value appropriate to the storage battery is obtained. <P>SOLUTION: When the operation of charging a storage battery from a direct-current power supply or an alternating-current power supply, the load circuit of a direct current-alternating current converter or an alternating current-alternating current converter is switched using a contact. The direct current-alternating current converter or alternating current-alternating current converter thereby limits a current by itself to charge the storage battery. For this reason, a conventionally used charger for charging storage batteries is not needed. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

本発明は鉄道車両用の搭載機器に関係し、車載の蓄電池へ充電を行う機能を有する電源装置に関する。 The present invention relates to a mounted device for a railway vehicle, and relates to a power supply device having a function of charging an in-vehicle storage battery.

以下、従来の電源装置について図２の回路図を参照しながら説明する。１は直流電源または交流電源、直流電源のときは直流交流変換器、交流電源のときは交流交流変換器とすることから２は直流交流変換器または交流交流変換器、３、５は三相開閉器、４は交流負荷、６は整流器、７はスイッチ、８は蓄電池、９は直流負荷である。
図２において充電動作はスイッチ７を開放し蓄電池８の両極に専用の充電器を接続し充電を行っている。 A conventional power supply device will be described below with reference to the circuit diagram of FIG. 1 is a DC power supply or AC power supply, a DC power converter is used for a DC power supply, an AC power converter is used for an AC power supply, 2 is a DC / AC converter or AC / AC converter, and 3 and 5 are three-phase switching 4 is an AC load, 6 is a rectifier, 7 is a switch, 8 is a storage battery, and 9 is a DC load.
In FIG. 2, the charging operation is performed by opening the switch 7 and connecting a dedicated charger to both electrodes of the storage battery 8.

充電動作をしているとき、三相開閉器３は開放状態にあり直流交流変換器または交流交流変換器２は動作せず、交流負荷４と直流負荷９への電力供給は行われない。
特開２００６―６９５１０公報 During the charging operation, the three-phase switch 3 is in an open state, the DC / AC converter or the AC / AC converter 2 does not operate, and power supply to the AC load 4 and the DC load 9 is not performed.
JP 2006-69510 A

図２において、専用の充電器を用いることなく蓄電池８を充電することを考える。専用の充電器が無い状態で充電動作を行わせた場合は、三相開閉器３とスイッチ７を閉じて交流負荷４へ電力供給を行いながら整流器６を経由して、直流負荷９へ電力供給を行うと同時に蓄電池８へ充電を行うことになる。 In FIG. 2, consider charging the storage battery 8 without using a dedicated charger. When charging operation is performed without a dedicated charger, power is supplied to the DC load 9 via the rectifier 6 while closing the three-phase switch 3 and the switch 7 and supplying power to the AC load 4. At the same time as charging, the storage battery 8 is charged.

蓄電池８の電荷蓄積量が非常に少ない場合、蓄電池８の電極両端に直流電圧が加圧された時に過大な電流が流れ、直流交流変換器または交流交流変換器２は過電流による保護停止により電力供給を停止し、交流負荷４と直流負荷９へ電力供給が停止し、よって充電動作も停止してしまう。 When the storage amount of the storage battery 8 is very small, an excessive current flows when a DC voltage is applied across the electrodes of the storage battery 8, and the DC / AC converter or the AC / AC converter 2 is powered by stopping the protection due to the overcurrent. The supply is stopped, the power supply to the AC load 4 and the DC load 9 is stopped, and the charging operation is also stopped.

そこで、専用の充電器を用いることなく、その目的を達成するための手段は、請求項１の発明によれば、直流電源を入力として、三相交流を発生させるインバータ回路の出力に、第一の開閉器を介して交流負荷に電力を供給する出力と、第二の開閉器を介して整流回路を通して蓄電池及び直流負荷に電力を供給する出力とを並列に給電するシステムにおいて、該蓄電池の充電が不充分な場合には、前記第一の開閉器を開放した状態で、前記インバータ回路の出力電圧を制御することにより前記蓄電池の充電電流を抑制し、かつ、前記蓄電池の充電完了後には前記第一の開閉器を投入して上記交流負荷に電力を供給することにより、前記蓄電池のための専用の充電器を具備しないようにしたことを特徴とする。 Therefore, according to the first aspect of the present invention, the means for achieving the object without using a dedicated charger is the first in the output of the inverter circuit that generates a three-phase alternating current with a direct-current power supply as an input. Charging the storage battery in a system in which an output for supplying power to the AC load via the switch and a power supply for supplying power to the storage battery and the DC load via the rectifier circuit via the second switch are connected in parallel. Is insufficient, the charging current of the storage battery is suppressed by controlling the output voltage of the inverter circuit with the first switch open, and after the charging of the storage battery is completed, The first switch is turned on to supply power to the AC load, so that a dedicated charger for the storage battery is not provided.

すなわち、直流電源が直流交流変換器に接続された電力源、当該電力源に三相開閉器を通して交流負荷に接続された回路と、当該電力源に三相開閉器を通して整流器に蓄電池が接続されかつ並列に直流負荷が接続される回路からなり、整流器から直接充電を行うことが出来ることを特徴とする。 A power source connected to a DC / AC converter, a circuit connected to the AC source through a three-phase switch to the power source, a storage battery connected to the rectifier through the three-phase switch and It consists of a circuit to which a DC load is connected in parallel, and can be directly charged from a rectifier.

請求項2の発明によれば、交流電源を入力とし整流回路を介して得た直流電力を入力として、三相交流を発生させるインバータ回路の出力に、第一の開閉器を介して交流負荷に電力を供給する出力と、第二の開閉器を介して整流回路を通して蓄電池及び直流負荷に電力を供給する出力とを並列に給電するシステムにおいて、該蓄電池の充電が不充分な場合には、前記第一の開閉器を開放した状態で、前記インバータ回路の出力電圧を制御することにより前記蓄電池の充電電流を抑制し、かつ、前記蓄電池の充電完了後には前記第一の開閉器を投入して上記交流負荷に電力を供給することにより前記蓄電池のための専用の充電器を具備しないようにしたことを特徴とする。 According to the invention of claim 2, the DC power obtained through the rectifier circuit with the AC power supply as an input, the output of the inverter circuit that generates a three-phase AC, the AC load through the first switch In a system in which an output for supplying power and an output for supplying power to a storage battery and a DC load through a rectifier circuit via a second switch are supplied in parallel, if the storage battery is insufficiently charged, With the first switch open, the charging current of the storage battery is suppressed by controlling the output voltage of the inverter circuit, and after the charging of the storage battery is completed, the first switch is turned on. By supplying power to the AC load, a dedicated charger for the storage battery is not provided.

すなわち、交流電源が交流交流変換器に接続された電力源、当該電力源に三相開閉器を通して交流負荷に接続された回路と、当該電力源に三相開閉器を通して整流器に蓄電池が接続されかつ並列に直流負荷が接続される回路からなり、整流器から直接充電を行うことが出来ることを特徴とする。 That is, an AC power source connected to an AC / AC converter, a circuit connected to an AC load through the power source through a three-phase switch, a storage battery connected to the rectifier through the three-phase switch to the power source and It consists of a circuit to which a DC load is connected in parallel, and can be directly charged from a rectifier.

以上説明したように本発明によれば、専用の充電器を用いることなく充電動作を行うことが出来、きわめて有用性の高いものである。 As described above, according to the present invention, a charging operation can be performed without using a dedicated charger, which is extremely useful.

図１は本発明の一実施例を示す回路図である。以下図1を参照しながら説明する。充電動作は直流電源または交流電源１を電源として直流交流変換器または交流交流変換器２の交流電力が三相開閉器５を閉じ整流器６で直流化し蓄電池８に充電される。このとき三相開閉器３は開放され交流負荷４への電力供給は行わない。充電動作は過電流による保護動作が発生しないように直流交流変換器または交流交流変換器２が蓄電池８に適切な電流を供給できるよう或る電流以上は流さないように電流制限を行い電力供給する。 FIG. 1 is a circuit diagram showing an embodiment of the present invention. This will be described below with reference to FIG. In the charging operation, AC power from a DC power source or AC power source 1 is used as a power source, and AC power from the DC / AC converter or AC / AC converter 2 is closed by the three-phase switch 5 and converted into direct current by the rectifier 6 and charged to the storage battery 8. At this time, the three-phase switch 3 is opened and no power is supplied to the AC load 4. In the charging operation, the DC / AC converter or the AC / AC converter 2 supplies current by limiting the current so as not to flow more than a certain current so that the DC / AC converter or the AC / AC converter 2 can supply an appropriate current to the storage battery 8 so that the protection operation due to overcurrent does not occur. .

蓄電池８の充電が完了すると三相開閉器３を閉じて交流負荷４へ電力供給される。 When charging of the storage battery 8 is completed, the three-phase switch 3 is closed and power is supplied to the AC load 4.
