Latest Patents
Etoh's latest patents include two remarkable inventions centered around power supply devices. The first, titled "Power supply device and arc machining power supply device," introduces a versatile power supply that supports both 200 V and 400 V series input power. It achieves this by switching the operation of an auxiliary switching circuit, effectively aligning with the inverter circuit during various output demands. For larger output requests, this device employs PWM (Pulse Width Modulation) control to precisely adjust the on pulse width of control signals. Conversely, for smaller outputs, it utilizes PSM (Phase Shift Modulation) control, optimizing the phase difference of control signals in real-time.
The second patent, "PWM-PSM controlled power supply with auxiliary switching circuit for soft-switching," refines power supply management further. This innovation distinguishes itself by performing PWM control when significant outputs are necessary, ensuring effective activation of switching elements within the inverter circuit and auxiliary switching circuit. During less demanding output situations, PSM control optimizes the timing of control signals, thereby enhancing efficiency through fixed ON pulse widths.
