Designing switching waveforms is a technique for mitigating a trade-off between loss and noise in switching power devices. A novel and simple method has been proposed to compute the gate waveform to realize a designed switching waveform. The gate cur

The switching waveform design, especially controlling and optimizing the slew rate, is an efficient technique to mitigate the trade-off between decreasing the loss and increasing the noise of the switching power device. The digital active gate driver

There is a trade-off between surge voltage and switching loss in power semiconductors, and it has been difficult to reduce both. In order to solve this problem, the digital gate drive method has been studied. However, the digital gate drive method ha

The world's smallest distributed-feedback laser modules using the miniature thermoelectric cooler (TEC) has been developed. By the virtue of reducing the heat load of the built-in TEC, the module has been successfully downsized to $\phi 5.6\times 12.
