Regulated voltage divider for voltage or current measuring circuit arrangement, has actuator with control input for control signal and setting connection for controlled setting current

摘要

The regulated voltage divider (1) has an actuator (2) controlled by a pulse-width modulated control signal (U20). The actuator has a control input (20) for the control signal, and a setting connection (21) coupled to a plate connection (11) at which the setting current (I21) controlled by the control signal impends. The regulated voltage divider has two inputs for feeding input voltage (U10). A plate voltage is fed through the divider connection. Independent claims are also included for the following: (a) the voltage measuring circuit arrangement using the regulated voltage divider; (b) and the use of the circuit arrangement for measuring current.
