This thesis continues the analysis of a Capacitively Isolated Low-Power DC-DC converter, building on previous work, by incorporating a control loop to regulate the output voltage under varying conditions and maximizing the system’s performance. To achieve this, a comprehensive mathematical model is develop to better understand the system’s behaviour and dynamics. The operating point is carefully selected to optimize performance by exploiting the sub-harmonics in the gain curve and Partially Damped Oscillations (PDO). This approach significantly reduces switching losses and ensures Zero Voltage Switching (ZVS) across all operating points. Various control strategies are presented, highlighting the advantages and disadvantages of each.
