Abstract

See full text

A circuit configuration for inductively heating a fuel injector, includes an injection valve heater coil having connections forming first and second nodes, a capacitor connected parallel to the heater coil, a first inductor connected between a positive pole of a supply voltage and the first node, a second inductor connected between the positive pole of the supply voltage and the second node, a first controllable switching element connected between the first node and a negative pole of the supply voltage, a second controllable switching element connected between the second node and the negative pole of the supply voltage, and a control unit connected to control inputs of the switching elements for applying a switch-on level to the control inputs when the voltage at the respective node connected to a switching element becomes 0 and for dimensioning a switch-on duration of the switching element according to a preset heating power.
