Overview:
This paper presents the circuit principle of a new high-power adjustable switching power supply. Using the Buck-type switching power supply topology, the MC33060 is controlled by a single PWM output and current-voltage feedback. The dual-output IR2110 driver chip is used to design a high-power, high-power switching power supply. Switching power supplies do not have high output voltages and powers in non-isolated topologies, and have circuits such as overcurrent protection. Based on the application of MC33060, this paper introduces the design method of adjustable switching power supply, and then explains the composition of the system and the role of each part in detail. The article concludes the characteristics of the system.
