Circuit arrangement for inductively heating a fuel injector valve

A circuit configuration for inductively heating a fuel injection valve, the circuit configuration comprising:

• an injection valve heater coil having connections forming a first node and a second node;
• a capacitor connected in parallel with said heater coil;
• a first inductance connected between a positive terminal of a supply voltage and said first node;
• a second inductance connected between the positive terminal of the supply voltage and said second node;
• a first controllable switching element connected between said first node and a negative terminal of the supply voltage, said first controllable switching element having a control input;
• a second controllable switching element connected between said second node and the negative terminal of the supply voltage, said second controllable switching element having a control input;
• and
• a control unit connected to said control inputs of said controllable switching elements, said control unit applying a respective switch-on level to said controllable switching elements when a voltage at a respective node to which a respective switching element is connected becomes 0 volt and dimensioning a switch-on duration of the respective switching element in accordance with a preset heating power.
