| Research Abstract |
This study proposes a dc/dc converter, which is driven by a controller called delta-sigma modulator. The dc voltage is converted to an ac voltage with switching devices. The ac current is maintained in sinusoidal waveform. The switching devices are turned on/off when the ac current becomes zero. As a result, the switching noise and loss are reduced. The proposed circuit has been tested with a simulation model and in circuit experiments.
