Embodiment 1
[0053] Example 1, such as figure 1 As shown, the detection device of the variable frequency compressor drive board externally receives the detection drive board and provides at least two isolated DC regulated power supplies.
[0054] The detection device includes a detection board with an MCU, a DC stabilized power supply, a display board, a DC voltmeter, and an AC voltmeter on the periphery of the detection board, and a relay for timing control is arranged on the detection board.
[0055] The detection board adopts two independently provided, mutually isolated +15V weak power supplies to detect the IPM and IGBT functional circuits on the drive board to be detected.
