Lightning protection for power supply of electronic equipment is an important problem of low-voltage lightning protection systems. In this paper, lightning characteristics of electronic equipment’s power supply are studied. Firstly impulse generator is developed. Then lightning characteristics tests for different powersupply, such as switch model power supply, are done. Test results show: diffe...

This paper proposes a bi-directional isolated DC/DC converter for the battery charger and discharger of Electric Vehicle to reduce power loss under light loads. The proposed consists two full-bridge inverters, an transformer, boost reactor, provides transmission, buck-boost conversion, zero-voltage-switching reactive suppression. Two semiconductors inverter in rectification side are turned off ...

Cascaded H-bridge multilevel power electronic converters generally require several dc sources. An alternative option is to replace all the separate dc sources feeding the H-bridge cells with capacitors, leaving only one H-bridge cell with a real dc voltage source. This will yield a cost-effective converter. However, the required capacitor voltage balancing is challenging. In this paper, using t...

This paper introduces a new bidirectional, isolated dc–dc converter. A typical application for this converter can be found in the auxiliary power supply of hybrid electric vehicles. A dual half-bridge topology has been developed to implement the required power rating using the minimum number of devices. Unified zero-voltage switching was achieved in either direction of power flow with neither a...
