摘要

摘要: 针对现有矿用电源存在取电不便、体积大、抗波动能力差、电路复杂、成本高等问题，设计了一种矿用超宽输入电压范围自适应电源。该电源采用输入串联型反激变换器，可降低功率开关管的电压应力，将超宽输入电压转换为稳定的直流电压。试验结果表明，在输入电压为AC85～900 V时，电源输出电压最大误差仅为1.1%，纹波电压不超过139 mV，效率高达87.4%；绝缘耐压试验中漏电流不大于1.53 mA，绝缘电阻不小于50 MΩ，满足GB 3836.4—2010《爆炸性环境第4部分：由本质安全型“i”保护的设备》中防爆要求。

Abstract: For problems of existing mine-used power supply such as inconvenient access, large volume, poor anti-fluctuation ability, complex circuit and high cost, a mine-used adaptive power supply with super wide input voltage range was designed. The power supply adopts input-series flyback converter, which can reduce voltage stress of power switching tube and convert super wide input voltage into stable DC voltage. The test results show that when input voltage is AC85-900 V, the maximum error of power supply output voltage is only 1.1%, ripple voltage is not more than 139 mV, and efficiency is 87.4%. In test of insulation withstand voltage, leakage current is not more than 1.53 mA and insulation resistance is not less than 50 MΩ, which meet explosion-proof requirements of GB 3836.4-2010 Explosive atmospheres Part 4: Equipment protection by intrinsic safety "i".
