A frequency converter includes an intermediate circuit capacitor at which an intermediate circuit voltage is present, an inverter for generating control signals with a variable frequency and a variable amplitude from the intermediate circuit voltage, and a circuit for measuring the intermediate circuit voltage. The circuit for measuring the intermediate circuit voltage includes a resistive voltage divider, the intermediate circuit voltage being applied to the first side of the resistive voltage divider and the second side of the latter being electrically connected to a reference potential, a capacitive voltage divider, the intermediate circuit voltage being applied to the first side of the capacitive voltage divider and the second side of the latter being electrically connected to the reference potential, at least one connecting node of resistors of the resistive voltage divider being electrically connected to a corresponding connecting node of capacitors of the capacitive voltage divider, and an evaluation unit which evaluates a measurement voltage generated by means of the resistive voltage divider and the capacitive voltage divider for the purpose of measuring the intermediate circuit voltage.
