| Outline of Final Research Achievements |
In this research, the tri-state switch control method to achieve a high speed and high accuracy regulation of the output voltage has been proposed. The controller blocks do not include any of amplifier or opt-coupler which occurs micro-second propagation delay or phase delay. These proposed features may not degrade the dynamic characteristic. The steady-state error is automatically compensated without any of integral control. Therefore, this proposed control method will be suitable for high frequency control like as MHz PWM control. By using simulation, the validation of the proposed operation for MHz-level switching frequency flyback converter is revealed. From the experimental results, 1.58% of the load regulation and 1.5% of the line regulation are confirmed at 1MHz switching frequency.
