Modified-structure frequency converter

The utility model provides a modified-structure frequency converter and belongs to the technical field of industrial control devices. The modified-structure frequency converter comprises a radiator, a power amplifier board, a power-supply drive board, a control board, and a baseboard which is used for installation of the radiator. The modified-structure frequency converter is characterized in that the power amplifier board is installed at one end of an upper portion of the radiator, and the power-supply drive board and the control board are positioned at the other end of the upper portion of the radiator in an overlapping mode. The technical scheme of the modified-structure frequency converter includes that the power amplifier board is installed at the one end of the upper portion of the radiator, and the power-supply drive board and the control board are positioned at the other end of the upper portion of the radiator in an overlapping mode, and therefore modularization is achieved due to improvement of integration degrees, an overall size of the frequency converter is lessened, and convenient installation is achieved.
