Abstract

The invention discloses a resolver output signal processing circuit, a motor controller and an automobile. The circuit includes a first resistor, a second resistor, a third resistor, a fourth resistor, and a first operational amplifier. One end of the first resistor is connected with the negative output end of the sinusoidal winding of the resolver, and the other end of the first resistor is connected with the inverting input end of the first operational amplifier; One end of the second resistor is connected to the inverting input terminal of the first operational amplifier, and the other endof the second resistor is connected to the output terminal of the first operational amplifier; One end of the third resistor is connected with the positive output end in the sinusoidal winding of theresolver, and the other end of the third resistor is connected with the non-inverting input end of the first operational amplifier; One end of the fourth resistor is connected to the noninverting input terminal of the first operational amplifier, and the other end of the fourth resistor is connected to a preset bias voltage. The resolver output signal processing circuit provided by the embodimentof the invention has the advantages of simple structure, convenient adjustment and reliable signal processing mode.

Description

technical field [0001] The invention relates to the technical field of output signal processing of a resolver, in particular to a resolver output signal processing circuit, a motor controller and an automobile. Background technique [0002] The resolver is a key component used in electric vehicles to obtain the speed and position of the motor. The resolver has two output windings, namely the sine winding and the cosine winding. These two output windings will generate differential signals including the speed and position of the motor rotor, and send them to the resolver decoder chip for decoding by the resolver decoder chip signal. . [0003] The resolver decoding chip has strict requirements on the voltage amplitude of the differential signal output by the sine or cosine winding, and each signal in the differential signal has strict requirements on the voltage amplitude of the reference ground. Therefore, the processing of the output signal of the resolver is very importan...
