摘要：Subject The abnormality of the DC voltage converter is detected immediately.Solution A chopper circuit for converting a DC voltage connected between a DC powersupply and a load, a DC voltage controller for controlling the DC voltage of the choppercircuit according to the output voltage command, and a gate signal controller for

controlling the switching element of the chopper circuit by the DC voltage controller In aDC voltage converter Output voltage command valueInput voltage value of input voltagedetector outputRipple current calculator for calculating ripple current with inductance ofinductorA ripple current detector for detecting ripple current of input current andAdifference between the ripple current value of the ripple current calculator output andthe ripple current value of the ripple current detector output is obtained, and anabnormality determination device is provided for detecting the abnormality of the DCvoltage converter when the value exceeds the predetermined value Diagram
