Efficient and compact power supply for robotic application

Robots require compact, power efficient and regulated power supplies for their efficient operation. This paper deals with the problem of developing such a power supply. A single-output zero voltage switching pushpull converter with low switching and conduction losses for robotic applications has been presented in this paper. The proposed converter is designed for outputs of 5 V/ 1 A with a switching frequency of 50 KHz. A prototype model of this converter is developed and was used to power a dc servo motor of 5V/1A/0.5Nm/950rpm . The results obtained from the experimental set-up are presented and analysed in detail. The results reveal the superiority of the proposed method.
