| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this research, the sufficient resolution of frequency and AD conversion of the micro control unit that is used in the digitally controlled LLC converter is discussed, and furthermore the appropriate value of the cutoff frequency is verified in the RC filter of the feedback circuits. Experiments were conducted for the 48V to 24V(5A) prototype converter. As a result, it is found that the frequency resolution of the MCU needs more than 2.14ns and AD conversion resolution needs more than 6.6bit. Moreover it is found that the cutoff frequency needs less than about 1/10 of the switching frequency. | |
