Latest Patents
Tachikawa's latest patents include a "Power Control System for Electrical Power Supply Modules." This invention features a control circuit designed to manage multiple power supply modules connected in parallel to deliver power to a single load. The control module converts analog data related to the voltage level applied to the load and compares it to a predetermined voltage level. It computes the voltage deviation and determines if it falls within acceptable limits. The module then sends a pulse width data signal to the power supply modules to regulate the power each module provides.
Another significant patent is the "Power Supply Control System Comprising a Plurality of Power Supply Units." This system includes several power supply units that generate various output voltages. It features a sequence control unit that manages the power on and off sequences of these units based on their output voltages. Additionally, a failure detection control unit responds to failure signals by sequentially turning off the affected units, ensuring a systematic approach to power management.
