This paper introduces an alternative implementation of the traditional LC filter, called hybrid LC filter (HLCF). The construction described in this paper contains two foil windings that integrate inductance and capacitance into one unit. The main aspects of the HLCF design are considered. The experimental data show that the device proposed here can be used, instead of traditional LC filters, as an...
Common mode (CM) electromagnetic interference in power lines are typically reduced with a CM filter, which consists of discrete capacitors and inductors. An air-cored EMI filter with CM choke and integrated X and Y capacitors utilizing the parasitic capacitance of the windings is proposed. Its benefits include better high frequency performance, reduced component count, and improved manufacturability...
Proportional-integration (PI) controller scheme is implemented to control the phase voltage of the customer-end single-phase inverter in a low-voltage DC (LVDC) distribution system. In the inverter output, the LC-filter is used. In order to avoid resonances caused by the filter, the feedback and the feedforward filteration is used. It is shown that basic PI control system cannot drive the steady-state...
Passive filter topologies used at the output of the customer-end inverter in a low-voltage DC-distribution (LVDC) network are compared. The comparison of filter topologies is based on the requirements set for the voltage quality and issues such as the physical size of the filter, losses, the complexity of the needed control and the cost. It is concluded that most of the losses of LVDC system are coming...
