[0059] Such as figure 1 As shown, the present invention includes three parts: analog sampling circuit, a control system, a strong electric circuit. Such as figure 2 As shown, this product requires 6 single-phase isolation transformers of 220V: 220V, 3 inputs, 3 output sides. One end of the input side three single-phase transformers is connected to the A phase, B phase, and the C phase of the grid through the wire, and the other end is connected together by a wire; one end of the output side three single-phase transformers is connected together by a wire, another One end is used as the A phase, B phase, and C phase output of the amplifier; in addition, the power portion of the present invention requires IGBT24, which constitutes three single-phase back-back converter;
[0060] The analog sampling circuit is a weak electric portion of the present invention. The analog sampling circuit requires an ADC chip to achieve, and the generation of PWM waves requires DSP to be implemented, ...
