POWER SOURCE
Document Type and Number:
Japanese Patent JPS5889069
Kind Code:
A
Abstract:
PURPOSE:To obtain the desired output waveform simply and inexpensively of configuration by connecting an amplifier to an operational amplifier, connecting a transformer to the amplifier, and producing the AC output having asymmetrical positive and negative voltages from the transformer. CONSTITUTION:An amplifier 33 is connected to an operational amplifier 21, and a transformer 34 is connected to the amplifier 33. At least one of power sources 31, 32 are constructed variably, thereby selecting the voltages of both in unequal relationship. The oscillation output of the operational amplifier 21 becomes asymmetrical at positive and negative voltages and no change occurs at the peak. And, the AC output having asymmetrical positive and negative voltages is produced from the transformer 34.
