Taking buck converter for example, this paper studies the non-linear characteristics and capacitance charge-balance control strategy of switching regulations systems under large-signal disturbance. In order to reduce the transient overshoot and recovery time of the output voltage under large-signal disturbance, the paper adopts capacitive charge-balance principle, deduces a new digital control algorithm...
The dynamic power loss in buck converter has been investigated in this paper, and the main contributions are as follows: (1) A transient analytic model for buck converter has been proposed to calculate the transient loss. This proposed model involves with some significant parasitic parameters which was always ignored in past; (2) Based on the proposed model, the total dynamic power loss in buck converter...
Based on high power-electronic ballast application, a novel soft switching technique for special buck converter has been investigated in this paper, which has many good performances such as high power, low loss and so on. The main contributions are as follows: 1. a new topology with soft switching has been proposed to match the electronic ballast; 2. the control approach for this new circuit has been...
In this paper, an approach by using the Agilent 4395A to measure the loop gain of the power supply has been deeply developed. The main issues have been investigated as the following: (1). Measurement techniques about the parasitic parameters of the filtering components will be studied. One is how to test of the electrolyte capacitor by Agilent 4395A; another is how to test dynamic inductance of filter...
