Problems solved by technology

In the existing technical solution, multiple linear power amplifiers are used to output different voltages respectively, and the equipment utilization rate is not high
At the same time, since linear power amplifiers are very expensive equipment, and the efficiency (output power / input power) of the equipment is not high, it will also cause problems such as high cost investment, low equipment utilization rate, excessive power supply demand and serious heat generation.
A single linear power amplifier can only output a single voltage range, and there are many restrictions on the application of multiple voltage ranges

Abstract

A multi-voltage output linear power amplifier includes at least one single-voltage range linear power amplifier, a switching unit connected to each of the single-voltage range linear power amplifiersfor outputting a plurality of AC voltages and / or a plurality of DC voltages. The technical scheme can expand the voltage output range or the power range, and realize the AC / DC output of different voltage levels.

Description

technical field [0001] The invention belongs to the field of electrical testing equipment, and in particular relates to a linear power amplifier with multi-voltage output. Background technique [0002] At present, linear power amplifiers use a single voltage output range, and in multiple voltage ranges, multiple linear power amplifiers are often used to output different voltages respectively. In the prior art solution, a plurality of linear power amplifiers are used to respectively output different voltages, and the equipment utilization rate is not high. At the same time, since the linear power amplifier is a very expensive device, and the efficiency (output power / input power) of the device is not high, it will also cause problems such as high cost investment, low equipment utilization rate, excessive power supply demand and serious heat generation. A single linear power amplifier can only output a single voltage range, and there are many restrictions on the application of...
