An aerosol-generating device is provided, including one or more DC power sources; a load network including an inductor and a capacitor connected in series; first drive circuitry connected to the DC power source(s) and across the network and being configured to provide a first voltage drop across the network; second drive circuitry connected to the DC power source(s) and across the network and being configured to provide a second voltage drop across the network, the second voltage drop being in an opposite direction to the first voltage drop; and a controller connected to the first and the second drive circuitry and being configured to control the first and the second drive circuitry so that both the first and the second voltage drops are provided across the network periodically and so that the second voltage drop is not provided across the network simultaneously with the first voltage drop.
