The invention discloses power conversion equipment and a charging pile. The power conversion equipment comprises a plurality of power converters and a plurality of leakage current sampling circuits. The power conversion device is used for turning off at least part of the first power converters when the sum of the leakage currents of the plurality of power converters is greater than a first current threshold, so that the sum of the leakage currents of the plurality of power converters is less than or equal to the first current threshold, the first power converter is a power converter whose leakage current is greater than a second current threshold among the plurality of power converters. The first current threshold value is the maximum leakage current allowed by the power conversion equipment, and the second current threshold value is the maximum leakage current allowed by the first power converter.
一种功率转换设备和充电桩,功率转换设备包括多个功率转换器和多个漏电流采样电路。功率转换设备用于:当多个功率转换器的漏电流之和大于第一电流阈值,关断第一功率转换器中的至少部分功率转换器,以使得多个功率转换器的漏电流之和小于或等于第一电流阈值,第一功率转换器为多个功率转换器中漏电流大于第二电流阈值的功率转换器。第一电流阈值为功率转换设备允许的最大漏电流,第二电流阈值为第一功率转换器允许的最大漏电流。
