Abstract: A capacitor-insulated semiconductor relay includes an RC oscillation circuit, a waveform regulation circuit, a booster circuit, a charging/discharging circuit, and an output circuit. The RC oscillation circuit generates first and second signals that are inverse in phase to each other. The waveform regulation circuit increases rise and fall times of the first signal, and rise and fall times of the second signal. Output signals from the waveform regulation circuit are respectively inputted to first and second high dielectric strength capacitors and that are provided in the booster circuit and connected in parallel to each other. The booster circuit receives the output signals from the waveform regulation circuit to generate a predetermined voltage. The output circuit is driven based on the predetermined voltage.
