| Abstract: | In order to apply electro-rheological fluid on automobile engine mount, controllable high-voltage power supply is needed. Principle of high voltage power supply based on PWM chip TL494 is introduced in this paper. The adjustment of the voltage is performed by digital potentiorneter controlled by MCU. The performance of the power supply is tested with digital oscillograph and the curve is obtained. The power supply have the advantage of compact size, high reliability, celerity and accuracy in voltage adjustment. It is proved that the power supply meet the requirements of electro-rheological fluid engine mount. |
