  • Zero Excess Energy Storage Transformer
    Publication number: 20230387911
    Abstract: A drive circuit configured to drive a load. The drive circuit comprises a transformer. The transformer comprises a transformer primary comprising one or more primary windings connected to arms that pass through a magnetic material. The transformer also comprises a transformer secondary comprising secondary windings connected to planar secondary conductors which pass through the inside of the arms. The drive circuit also comprises a voltage source configured to apply a voltage across the transformer primary.
    Type: Application

  • Driving variable capacitive loads
    Patent number: 10814617
    Abstract: Circuitry for driving a variable capacitive load comprising: a variable capacitive load; a digital control circuit configured to generate a digital drive signal; and a drive circuit configured to convert the digital drive signal into an analogue drive signal, the analogue drive signal forming a drive waveform for charging the variable capacitive load, the drive circuit comprising a slewing circuit configured to drive a time dependent voltage component of the drive waveform; wherein the digital control circuit is configured to modify the digital drive signal for each charging cycle so as to match the time dependent voltage component of the drive waveform to the variable capacitive load.
