Abstract:
A switch mode DC-AC converter driven oscillation system which always works on square wave driving, soft-switching and resonant conditions supported by the following techniques is disclosed. {circle around (1)} the techniques composed of totally analog circuitry to dynamically detect the innate resonant frequency of the system through comparison between the phases of the gate driving and zero voltage or current crossing signals of the main oscillation of the system and to drive the system with the detected innate resonant frequency to realize resonant operation and soft-switching. Based on different types of PLL technologies, two of such techniques are disclosed. {circle around (2)} the technique to realize a Voltage Controlled Soft-switching Capacitor (VCSC) to compensate the innate resonant frequency or to adjust the output voltage or power of the system through its tuning/detuning effect. The disclosed techniques can be combined to realize “square wave driving, soft-switching and resonant” systems which operate in either variable or fixed frequency conditions.

Claim (Index 5):
The switch mode DC-AC converter driven oscillation system in  claim 1  wherein the VCSC is configured to adjust an output voltage and power of the system, wherein:\n the VCSC is connected as a parallel or serial tuning capacitor in the secondary side resonant tank; \n an average equivalent capacitance of the VCSC is adjusted by a control voltage from the PI controller; \n the PI controller monitors fluctuations of the output voltage of the system and outputs the control voltage to adjust the average equivalent capacitance of the VCSC for compensating the fluctuations of the output voltage of the system making it stabilized.
