| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In the feedback circuit, the frequency characteristics of the controller affect the stability and transient response characteristics. In the case of LLC converters, a photocoupler is often used to isolate the feedback circuit, but since the photocoupler has a phase delay element, the frequency characteristics Adversely affect. In this paper, we propose a circuit system in which the control circuit of the LLC converter is insulated with a pulse transformer to improve the stability of the system. As a result, it was confirmed that the control method using the pulse transformer has a large phase margin and excellent load transient response characteristics. | |
