Abstract

The invention discloses an output voltage multiplier circuit for a programmable power signal source, comprising a differential amplifier circuit, an op amp power supply, a second power amplifier, a third power amplifier, an inverter, and a power supply. The differential amplifier circuit is connected to Va and the power amplifier system reference point GND, and the output is connected to the second power amplifier and the inverter. The second power amplifier outputs the Ua. The inverter output is connected to the third power amplifier. The third power amplifier outputs the -Ua. The power source is respectively connected to the second power amplifier and the third power amplifier. The op amp power supply is respectively connected to the differential amplifier circuit and the inverter. The -Ua is connected to the GND. The output voltage multiplier circuit for the programmable power signal source doubles the amplitude of the voltage output of the existing program-controlled power signal source, and has an excellent response speed and a high waveform playback effect.

Description

technical field [0001] The invention relates to the field of power distribution automation terminal testing, in particular to a program-controlled power signal source output voltage multiplication circuit. Background technique [0002] In the production, debugging and on-site testing of distribution automation terminals, the programmable power signal source is required to generate controllable voltage and current signals, which are input to the distribution automation terminals to determine whether their functions and performance are normal. [0003] The output voltage of the existing program-controlled power signal source can only reach AC 120V. For some distribution automation terminals working on the AC 220V system, especially the distribution automation terminals working on the AC 220V system that integrate supply and acquisition, it cannot meet the test requirements. . [0004] Analyze the existing programmable power signal voltage output structure, such as figure 1 A...
