Frequency & duty cycle control considerations for soft-switching buck chopper
This paper presents considerations on the switching frequency and duty cycle & operating equations of softswitching BUCK chopper. These considerations are discussed and applied to selected soft-switching families such as ZVS-QRC, ZCS-QRC, ZVS-QSW-CV, ZCS-QSWCC, ZVT-PWM and ZCT-PWM [1]. The limitations on switching frequency and duty cycle are derived in terms of: chopper input voltage (Vg), cho...
متن کاملBuck Converter with Soft-Switching Cells for PV Panel Applications
In power conversion of photovoltaic (PV) energy, a hard-switching buck converter always generates some disadvantages. For example, serious electromagnetic interference (EMI), high switching losses, and stresses on an active switch (metal-oxide-semiconductor-field-effect-transistor, MOSFET), and high reverse-recovery losses of a freewheeling diode result in low conversion efficiency. To release ...
متن کاملSoft Switching Buck Converter for Battery Charging With MPPT
Photovoltaic power generation system implements an effective utilization of solar energy, but generally has very low conversion efficiency. Maximum power point tracking (MPPT) is used in photovoltaic (PV) systems to maximize the photovoltaic array output power, irrespective of the temperature and irradiation conditions and of the load electrical characteristics. A MPPT system has been developed...
متن کاملThree-phase soft-switching inverter for induction motor drives
A zero-voltage transition (ZVT) soft-switching inverter for an induction motor drive is developed. The proposed soft-switchng inverter is formed from the traditional pulse-wi dth modulated (PWM) inverter by simply augmenting with auxiliary resonant circuits, and the soft switching is acheved through applying PWM switching control signals with suitable delays for the main and auxiliary switches....
متن کاملA New Topology of Bidirectional Buck-Boost dc/dc Converter with Capability of Soft Switching and input Current Ripple Cancellation
In this paper, a new bidirectional buck-boost dc-dc converter with capability of soft switching and zero input current ripple is proposed. The coupled inductor is used in the proposed converter to eliminate the input current ripple. In the proposed converter, zero voltage switching (ZVS) and zero current switching (ZCS) can be obtained for the main and auxiliary switches, respectively. In addit...
