Title:
コンデンサをあらかじめ定めた設定ポイントまで充電および放電するための装置および方法
Document Type and Number:
Japanese Patent JP2006512034
Kind Code:
A
Abstract:
An apparatus using electrically stimulated smart material requires a power source to stimulate the material. This power source has three main functions, (1) to apply a known voltage potential across the smart material, (2) to convert from the control voltage to a level suitable for the smart material, and (3) to regulate the voltage based on a control input. The power source is a DC to DC converter with special properties achieved by supplying a variable stimulating voltage or actively discharging the actuator. The circuit also provides a dead band, or hysteresis, between the charge point and discharge point. When this circuit is applied with a proportional, mechanically leveraged smart material actuator, a general-purpose industrial actuator becomes a cost-effective solution.
