Abstract: This application discloses a voltage conversion circuit, a voltage converter, and an electronic device. The voltage conversion circuit mainly includes a detection circuit having a first detection resistor and a second detection resistor, and a buck-boost circuit of an H-bridge structure. The first detection resistor is connected between one input end of the buck-boost circuit and one bridge arm of the H-bridge structure, the second detection resistor is connected between one output end of the buck-boost circuit and the other bridge arm of the H-bridge structure, and the detection circuit may output a current detection signal based on resistor voltages of the first detection resistor and the second detection resistor.
