PIEZOELECTRIC RELAY SWITCHING CIRCUIT |
摘要 |
<p>To control the operation of a piezoelectric relay, control circuitry is disclosed for direct ohmic connection to a utility AC source to draw the minimal power required to actuate the relay's bimorph member pursuant to selectively switching power current through either one of two separate loads. The control circuitry, which is largely implimented in a single integrated circuit chip, utilizes isolating resistance and the capacitances of a voltage doubler circuit and the piezoceramic plate elements for transient suppression and circuit protection.</p> |
