基于压电变压器的自激振荡回路中的最佳相移

A new method is implemented in designing of self-oscillating loop for driving piezoelectric transformers (PT). The implemented method is based on combining both analog and digital control systems. Digitally controlled time delay through the self-oscillating loop results in very precise frequency control and ensures optimum operation of the PT in terms of gain and efficiency. Time delay is implemen...
