This paper proposed sliding mode controller with fuzzy neural network estimator using 8-bit microcontroller in motor fan system (MFS). MFS wind flow has nonlinear dynamic behavior. We use fuzzy and neural network theory to estimate the lumped uncertainty in MFS. The estimator of adaptive laws is obtained by using the Lyapunov function. The low cost 8-bit microcontroller and Microsoft visual basic...
This paper presents an interleaved soft switching converter to achieve the features of zero voltage switching (ZVS) turn-on for power switches, zero current switching (ZCS) turnoff for rectifier diodes at full load, less transformer secondary winding with full-wave diode rectifier topology, and balance primary currents with series connection of the transformer secondary windings. Two circuit modules...
This paper presents the system analysis, design consideration and implementation of a Zero Voltage Switching (ZVS) DC-DC converter with series connected transformers. The buck-type converter with active snubber circuit is proposed in order to limit voltage stress on power switch and to achieve ZVS turn-on. The ZVS turn-on of switches is implemented in the transition interval of two complementary switches...
