RCC type switching power supply application circuit principle

Probe domestic switch needle KG-300K needle head diameter is 3.0mm normally open switch needle

Overview:
In this paper, the RCL-type switching power supply application circuit principle is analyzed and designed in detail, and the circuit simulation is carried out through computer simulation. Secondly, the RCC device was applied to the charger for actual testing, which was verified with the theoretical values, and then analyzed the device test results and the problems that need to be further solved. Finally, the conclusion is given. Although there are three problems such as "starting current is too large", the scheme basically overcomes the shortcomings of the separate RCC scheme, and the efficiency is more than 65%, which is one of the ideal RCC switching power supply devices.
