[0034] Further, as the second embodiment of the inverter air conditioner circuit board provided by the present invention, based on the first embodiment of the compressor control system of the present invention, in this embodiment, the PCB of the inverter air conditioner circuit board is double-sided, It can be wired on both sides. The two wires near the connecting side of the DC bus are located on both sides of the PCB, as shown in the figure, 1011 is located on the front of the PCB, and 1021 is the dotted line located on the back of the PCB, because these two DC buses They are respectively located on both sides of the PCB board, so the distance between the two wirings can be further shortened, and the projections of the two can be completely overlapped. At this time, the distance between the two is the thickness of the PCB, which is minimized and can further reduce the DC bus circumference. The formed area further reduces the interference to weak current parts and external pow...

The invention provides a circuit board for a frequency conversion air conditioner and the frequency conversion air conditioner. A bridge rectifier, a filter capacitor, a first IPM module, a MCU and asecond IPM module are arranged on a PCB; a direct current bus from an electrolytic capacitor is connected with the first IPM module and the second IPM module; the first IPM module and the second IPM module are respectively close to two sides of the PCB; the MCU is arranged between the first IPM module and the second IPM module; two conductors of the direct current bus connected with the first IPMmodule and the second IPM module are close to a connecting side of two sides of the PCB; parts, close to the connecting side, of the direct current bus, are arranged in parallel, so that the area of apart defined by the direct current bus can be small as much as possible, further the interference on an MCU control part with weak current and external power supply is reduced, reliability and stability of driving a load to run in the circuit board of the frequency conversion air conditioner are improved, and EMI requirements are met.
Description
technical field [0001] The invention relates to the field of frequency conversion air conditioner control, in particular to a frequency conversion air conditioner circuit board and a frequency conversion air conditioner. Background technique [0002] The outdoor unit circuit board of the existing inverter air conditioner includes an IPM module for driving a compressor IPM (Intelligent PowerModule, Intelligent Power Module) module and a DC motor of an outdoor fan, and its controller MCU needs to control these two IPM modules at the same time. The high-voltage part of the two IPM modules operates with a large current, so the layout and wiring design requirements of the relevant components of the entire outdoor motor circuit board are high, so that the outdoor load can run stably and meet EMI (Electromagnetic Interference, electromagnetic interference) requirements. [0003] The above content is only used to assist in understanding the technical solution of the present inventio...
