Embodiment Construction

[0014] attached figure 1 The middle unit 1 is a settable arbitrary waveform signal generation unit, the signal frequency range is from 0Hz to the limit operating frequency allowed by the device, and its signal complexity covers positive and negative DC components, fundamental wave integer multiplied or non-integer multiplied frequency waveforms, Any combination of aperiodic and asymmetrical waveforms. The signal is linearly amplified in voltage by the linear voltage amplifying unit 2 , then linearly amplified in power by the linear power amplifying unit 3 and then output to the load 7 . In order to ensure the high efficiency of the linear power amplifying unit 3, its power supply does not use a traditional DC power supply, but an arbitrary waveform ripple voltage equivalent to the instantaneous amplitude of the linear voltage amplifying unit 2, so that the linear power amplifying unit 3 outputs to the load The difference between the instantaneous value of the arbitrary wavefo...

Abstract

Disclosed converter is combined from signal generation unit for arbitrary waveform, power amplification unit in switch linear recombination type, and flexible pulse formation unit, which is capable of changing pulse frequency and duty ratio triggered by switch at random. Power level supply waveform coincident to preset signal in arbitrary waveform is obtained on load. The converter possesses strong robustness for resistive, capacitive, inductive and non-linear load so as to realize fidelity, tracking and magnifying in power level for arbitrary waveform. The magnified frequency band of the converter is full band from zero frequency to ultimate working frequency of device. Ripple voltage dropped on power tube of linear power amplification unit is controlled at saturation pressure level of tube so as to make power amplification unit at higher efficiency.

Description

Technical field: [0001] The invention relates to a power electronic power conversion technology. Background technique: [0002] In order to simulate various regular and irregular strong interference phenomena in the fields of nature, economic construction and national defense, in order to obtain effective test data and conduct pre-plan research on preventive measures, an arbitrary waveform non-standard power supply device with a certain power is required. For example, the state simulation of various disturbances and harmonics that may be encountered during the operation of power system equipment; the test of the seismic strength of hydropower stations and dams; the judgment of the anti-destructive ability of a certain facility; Harsh environments, etc., all need to flexibly manufacture arbitrary waveform signals that carry energy and apply them to the target. [0003] In order to realize the power transmission of high force energy density, the existing foreign devices of th...
