چکیده
Abstruct-This paper proposes a transformer assisted PWM zero voltage switching Neutral-Point-Clamped (NPC) inverter. With the assistance of a transformer assisted small rating lossless auxiliary circuit, the main switches work with zero voltage switching without suffering from any voltage/current spikes, under simple explicit control. The technique allows for higher operating frequency and better device utilization of the NPC inverter. Operation, analysis, designing as well as testing results from a 7kW prototype are presented in details.

متن کاملA New N-Level Inverter Based on Z-NPC
First of all, in this paper, the topology and operation of the three-phase three-level Z-source inverter based on neutral-point-clamped (Z-NPC) are studied. Moreover, different combinations of permissible switching states and control signals are explained for this inverter. In this paper, the topology of the three-phase three-level Z-NPC inverter is extended for an n-level state. Also, a combin...
متن کاملSteady-state analysis and simulation of a BJT self-oscillating ZVS-CV ballast driven by a saturable transformer
The steady-state oscillation of a zero-voltageswitching clamped-voltage self-oscillating ballast driven by a saturable transformer is analyzed and simulated. Its selfoscillating operation is divided into six stages according to the hysteresis B–H loop of saturable transformer cores. Stage-wise circuit analysis shows the saturable transformer limits the lamp current and dominates the switching f...
متن کاملFeedforward Ripple Cancellation for a Full-Bridge Converter - Applied Power Electronics Conference and Exposition, 2000. APEC 2000. Fifteenth Annual IEEE
AbstmctThis paper presents a feedforward ripple cancellation technique for use with a full-bridge DC-DC converter. The full-bridge is used to energize an inductive coupling that serves as an isolating connector in a battery charging system. Feedforward ripple cancellation prevents large ac currents from flowing into the battery terminals in response to unavoidable ac ripple on the inverter inpu...
