A charging device has a resonant circuit that includes a transmitting coil. The charging device also has a driver circuit configured to power the resonant circuit, a pulse width modulator and a controller configured to provide a control signal to the pulse width modulator the control signal configuring the pulse width to provide a modulated drive signal to the driver circuit. The pulse width modulator is configured to provide the modulated drive signal to the resonant circuit. The resonant circuit is configured to operate as a low-pass filter that blocks frequency components of the modulated drive signal that correspond to the reference signal. The driver circuit is configured to use the modulated drive signal to produce a charging current in the resonant circuit. The charging current causes power to be wirelessly transferred to a receiving device through the transmitting coil."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Resonant class D wireless transmitter","description":"Systems, methods and apparatus for wireless charging are disclosed.
