The measured waveforms of the 6 V output LLC resonant converter operating at full 150 A load current and 1 MHz switching frequency is shown in Fig.16.Soft switching is achieved as evident by the absence of oscillation and overshoot.The total system efficiency including the overhead power consumption at 40 V，48 V and 60 V input voltage is presented in figure 17，which achieved a peak efficiency of 98%and 98.1%at 48 V and 60 V respectively，and above97%efficiency over a wide output power range.The power density exceeds 1 100 W/in3.
