A tuned circuit has a resonant frequency when connected to a resonant load. The tuned circuit receives inverter output and generates a driving signal. Frequency of the inverter output and frequency of the driving signal substantially equal the resonant frequency of the tuned circuit. The tuned circuit boosts the inverter output to generate the driving signal such that a voltage of the driving signal is greater than a voltage of the inverter output. A feedback portion receives the inverter output and phase-shifts it to generate an inverter control signal. The feedback portion provides the inverter control signal to the input of the controlled switch to control switching operations of controlled switch. The driver self-oscillates at the resonant frequency due to the feedback portion phase-shifting the inverter output to generate the inverter control signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Piezoelectric driver","description":"A driver circuit includes an inverter having a controlled switch with an input for controlling switching operations.
