Based on the characteristics of switching power supply, this paper, taking MC34063A IC as the research object, has proposed the design, realized design of single-transistor positive buck DC-DC converter through calculation and component selection, and simulated the circuit of the design using Saber software. When the input voltage is 15V~25V, the output voltage has been stabilized within the scope...
A three-phase ac-to-dc power transistor converter that is suitable for speed control of a dc motor and for a variable dc power supply is investigated. The availability of power transistors of fairly high power rating has made the task of ac-to-dc conversion relatively easy due to simplification of the converter circuit configuration. The external performance characteristics of the power transistor...
