| Abstract |
A simple and effective single-sensor estimation method is described in this paper. Using only one
sensor, the proposed method can provide all necessary information for feedfoward and feedback control
and parameter estimation. The principle is demonstrated in a commonly used half-bridge converter
under high-frequency operation. The input voltage, load resistance, load voltage and output power are
estimated in this example. It is found that the proposed method can estimate these variables and
parameters with high degree of accuracy. The method can reduce the number of sensors and eliminate
the requirement of complex isolated feedback circuitry in power converters. |
