【考案の詳細な説明】
本考案は、±Ｅの両電源から実の片電源を作り負荷に与
える倍電圧整流回路の改良に関する。[Detailed Description of the Invention] The present invention relates to an improvement in a voltage doubler rectifier circuit that creates a real single power supply from dual power supplies of ±E and supplies it to a load.
一般にこの種倍電圧整流回路は第１図に示すように、正
の直流電源＋Ｅ１負の直流電源−Ｅ、ダイオードＤ１．
Ｄ２、コンデンサＣ１，Ｃ２およびＡ接点とＢ接点とを
発振器Ｏの出力によって交互に切換えるスイッチＳＷと
を有している。In general, this kind of voltage doubler rectifier circuit, as shown in FIG. 1, consists of a positive DC power supply +E1, a negative DC power supply -E, a diode D1.
D2, capacitors C1 and C2, and a switch SW that alternately switches the A contact and the B contact by the output of the oscillator O.
スイッチＳＷがＡ接点（−Ｅ側）に接続されていると、
コンデンサＣ工に顧なる電圧が充電される。When switch SW is connected to A contact (-E side),
The relevant voltage is charged to the capacitor C.
スイッチＳＷがＢ接点（基準点側）に切換わるとＣ工の
顧なる電圧がダイオードＤ２を介してコンデンサＣ２に
移り、負荷ＲＬに顧の電圧を与える。When the switch SW is switched to the B contact (reference point side), the voltage connected to the circuit C is transferred to the capacitor C2 via the diode D2, and the voltage applied to the load RL is applied.
とこころで倍電圧整流回路では出力電圧ＥＯを沃塩上に
上げることは原理的にできないが、顧より少し下げるこ
とはできる。By the way, although it is not possible in principle to raise the output voltage EO higher than that of the iodine with a voltage doubler rectifier circuit, it is possible to lower it slightly.
この手段として従来は、出力電圧調整用の可変抵抗器Ｒ
を第２図のように負荷ＲＬに並列に接続したり、第３図
のようにＲＬに直列に接続することが行われている。As a conventional means for this purpose, a variable resistor R for adjusting the output voltage has been used.
are connected in parallel to the load RL as shown in FIG. 2, or in series to the load RL as shown in FIG.
しかしながら第２図の回路では消費電流が増える欠点が
あり、第３図の回路では負荷変動が出力電圧に大きく影
響する欠点がある。However, the circuit shown in FIG. 2 has the disadvantage that current consumption increases, and the circuit shown in FIG. 3 has the disadvantage that load fluctuations greatly affect the output voltage.
本考案の目的は、上述の如き欠点のない出力電圧調整手
段を有する倍電圧整流回路を実現するにある。The object of the present invention is to realize a voltage doubler rectifier circuit having an output voltage adjusting means that does not have the above-mentioned drawbacks.
第４図は本考案回路の一実施例を示す接続図である。FIG. 4 is a connection diagram showing one embodiment of the circuit of the present invention.
第４図において、第２図および第３図の従来例と異ると
ころは、出力電圧調整用の可変抵抗器Ｒを正の直流電源
十ＥとダイオードＤ１との間に接続した点である。The difference in FIG. 4 from the conventional examples shown in FIGS. 2 and 3 is that a variable resistor R for adjusting the output voltage is connected between the positive DC power source 1E and the diode D1.
このように構成すると可変抵抗器Ｒの大きさに応じてコ
ンデンサＣ□への充電がおさえられ、出力電圧Ｅｏの調
整ができる。With this configuration, charging of the capacitor C□ can be suppressed depending on the size of the variable resistor R, and the output voltage Eo can be adjusted.
すなわちＲの抵抗値が零のとき出力電圧Ｅｏが最大で消
費電流も最大となり、抵抗値を上げていけば出力電圧Ｅ
ＥＯが下がると同時に消費電流も下がる方向になる。In other words, when the resistance value of R is zero, the output voltage Eo is maximum and the current consumption is also maximum, and as the resistance value is increased, the output voltage E
As EO decreases, current consumption also decreases.
またコンデンサＣ２の容量が適当であれば負荷変動の影
響も小さい。Furthermore, if the capacitance of the capacitor C2 is appropriate, the influence of load fluctuations will be small.
以上説明したように本考案の倍電圧整流回路によれば、
消費電流を増やすことなく、また負可変動の影響を大き
くすることなく出力電圧の調整を行うことができる。As explained above, according to the voltage doubler rectifier circuit of the present invention,
The output voltage can be adjusted without increasing current consumption or increasing the influence of negative variable fluctuation.
