This thesis primarily aims to achieve the most highly optimal design for LLC-SRC in terms of safety, stability and reliability. The main circuitry used is LLC-SRC as it is able to achieve high efficiency, low level of EMI emissions, and high power density. Investigation of LLC-SRC design was conducted by using the L6599 PWM IC of STMicroelectronics. The optimization design of LLC-SRC was achieved to implement a 90W PSU. It is able to achieve high efficiency and meet EPA regulation. The electrical functions compares with experimental results and a laboratory prototype are measured in detail. The electrical functions are satisfactory.
