I intend to build a wireless power charger using the power transmitter design A12 on the WPC manual and having some difficulty. And I need some guidance. Based on the circuit diagram, I will step down the voltage to approx 5V to power the full-bridge inverter. I have never worked with inverters and need some clarification. Based on the attached file, when it states the operating freq for the inverter is 110 - 205KH, how to I design a circuit that will operate within than range? Any thread that could refer me to how to build the inverter? Any guidance will be be greatly appreciated.
