| Abstract |
This paper implemented a 10W DC/DC converter based on the piezoelectric transformer (PT) for the space application. The PT operating frequency is fixed at zero voltage switching (ZVS) conditions in order to obtain the good efficiency. The input driving circuit of the PT was adopted the half-bridge circuit with a filtering inductor. The full-wave rectifier was adopted to obtain the DC load voltage. To fix the switching frequency and the duty cycle simultaneously, the hysteresis control and the burst mode operation were used. The results show the difficulty of this hysteresis control in the burst-mode operation is the accuracy of the load voltage. |
