Abstract

A voltage converter may include a first voltage sensor and a second voltage sensor both configured to measure an output voltage of a voltage converter circuit and a controller configured to execute a feedback control for the voltage converter circuit such that a voltage difference between a target voltage and a measured value of the first voltage sensor becomes zero and configured to execute a predetermined error process in a case where a measured value of the second voltage sensor exceeds a predetermined voltage upper limit value. The controller may execute the feedback control such that a voltage difference between a correction target voltage and the measured value of the first voltage sensor becomes zero while the measured value of the second voltage sensor exceeds a voltage threshold which is less than the voltage upper limit value.

Claims (11)

1. A voltage converter comprising;

a voltage converter circuit;

a first voltage sensor and a second voltage sensor both configured to measure an output voltage of the voltage converter circuit; and

a controller configured to execute a feedback control for the voltage converter circuit such that a voltage difference between a target voltage and a measured value of the first voltage sensor becomes zero and configured to execute a predetermined error process in a case where a measured value of the second voltage sensor exceeds a predetermined voltage upper limit value, wherein

the controller executes the feedback control for the voltage converter circuit such that a voltage difference between a correction target voltage and the measured value of the first voltage sensor becomes zero while the measured value of the second voltage sensor exceeds a voltage threshold which is less than the voltage upper limit value, the correction target voltage obtained by subtracting an offset voltage from the target voltage.

2. The voltage converter as in claim 1 , wherein

the offset voltage is a value obtained by subtracting the voltage threshold from the measured value of the second voltage sensor.

3. The voltage converter as in claim 1 , wherein

the voltage threshold is a value obtained by subtracting a tolerance of the second voltage sensor from the voltage upper limit value.

4. The voltage converter as in claim 1 , wherein

the predetermined error process is a process of stopping the voltage converter circuit.
