| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | To design a controller for a switching power supply, it is necessary to know the characteristics of the main circuit and modulator of the converter to be controlled. However, since the influence on the phase characteristics of the modulator is small outside the high frequency region, the phase characteristics of the modulator have been designed by simple modeling. Incidentally, converters are required to have high responsiveness so that they can quickly respond to fluctuations in output voltage. The wider the bandwidth, the faster the response. When designing a wideband power supply, it is necessary to model the phase characteristics of the modulator in detail because the influence on the phase characteristics of the modulator cannot be ignored in the high frequency region. When the main circuit was modeled using the state averaging method, the time ratio modulator was modeled using three elements: sample hold, delay time, and inverse sample hold. As a result, we clarified the relationship between the frequency characteristics and the duty ratio of the duty ratio modulator. As a time ratio modulator, trailing edge, leading edge, and both edge digital PWM were modeled. | |
