| Abstract: | This paper introduces a kind of the design of inverter power supply with high reliability and flexibility, the structure of the main circuit and the control cirtuit are discussed and analyzed in detail. The power supply use push-pull step-up transformer and full-bridge voltage MSPWM inverter, the PWM controller is KA7500B. It provides functions of over-vohage, under-voltage and over-temperature protection. The power works stably in practice and thus it is worth to be promoted. |
