Abstract

The invention discloses a power converter detection test bench which comprises a base. The top of the base is movably connected with a first fixing plate, the top of the first fixing plate is providedwith a second fixing plate, and the two sides of the top of the second fixing plate are each provided with a first clamping plate. The left side of an inner cavity of the base is fixedly connected with a motor, and a rotating shaft of the motor is fixedly connected with a first gear. Through arranging the motor, the effect of driving the first gear to rotate is achieved. Through arranging a firstgear and a second gear, the effect of driving the rotating shaft and the first fixing plate to rotate is achieved, and the effect of adjusting the angle of the first fixing plate is also achieved. Through the second fixing plate, the effect of placing the power converter is achieved. Through the first clamping plate, the effect of fixing the power converter is achieved. Through the electric telescopic rod, the effect of adjusting the height of the first clamping plate is achieved, and through the test bed, people can maintain and detect the power converter conveniently, and people can use thetest bed conveniently.

Description

technical field [0001] The invention relates to the technical field of power converters, in particular to a test bench for power converters. Background technique [0002] The power converter uses the measured phase to obtain an AC sine wave reference signal that is in phase with the input voltage. The multiplier obtains the converter current command according to the signal. In addition, the approximate differentiator differentiates the input current, and the band-pass filter The resonant frequency component is measured, the proportional device multiplies the resonant frequency component by the gain coefficient, the subtracter subtracts the multiplied result from the converter current command, the current control amplifier and the PWM modulation circuit control the converter, so that the output of the subtractor is equal to The current of the converter is consistent. The power converter test bench is a workbench for maintenance, testing and experimentation of the power conver...
