| Abstract [eng] |
The aim of this work is to investigate power supply based on half bridge topology and offer a solution for optimizing power supply then the capacitive load is connected, and it varies from 1 ultrasonic transducer to 100 units. Applied methods: scientific literature analysis, work with LTSpice program. In this paper were analyzed power factor compensation method, low frequency filter for signal synthesizing and main topologies of pulse width modulation. According to the analyzed theory, initial system model was created in LTSpice environment. Subsequently, with the help of a compiled model, the investigations and the determination of the power loss induced dependence on variable load quantity are collected for further analysis of the system. According to the method reviewed in the literature analysis, an optimized system model has been created. An experiment reiterated with an optimized model, during simulation data was collected. This data was compared to the original system model. |
