IEC 62093:2022规定了适用于地面光伏（PV）系统长期运行的功率转换设备（PCE）设计资质的IEC要求。 本文件涵盖了用于地面光伏应用的电子功率转换设备。术语PCE是指用于将电力电子转换成关于电压、电流和频率的另一种电力的设备和部件。本文件适用于在IEC 60721-3-3和IEC 60721-3-4中定义的室内和室外气候条件下使用的PCE。这样的设备可以包括但不限于并网和离网DC到AC PCE、DC到DC转换器、电池充电器转换器和电池充电控制器。本文件涵盖了连接到标称不超过1 500 V DC最大电路电压的光伏阵列的PCE。第二版取消并取代了2005年出版的第一版。与上一版相比，此版本包括以下重大技术变更: a.标题已修改。 b.本版侧重于功率转换电子（PCE）的设计鉴定，并消除了与其他系统组件平衡的鉴定测试相关的条款。 c.虽然许多条款标题与第一版相同，但已进行了实质性更改。 d.第一版规定了地面光伏(PV)系统中使用的系统平衡组件的设计资格要求，而本版仅限于功率转换设备。 e.测试方案已更改。

IEC 62093:2022 lays down IEC requirements for the design qualification of power conversion equipment (PCE) suitable for long-term operation in terrestrial photovoltaic (PV) systems.
This document covers electronic power conversion equipment intended for use in terrestrial PV applications. The term PCE refers to equipment and components for electronic power conversion of electric power into another kind of electric power with respect to voltage, current, and frequency. This document is suitable for PCE for use in both indoor and outdoor climates as defined in IEC 60721-3-3 and IEC 60721-3-4. Such equipment may include, but is not limited to, grid-tied and off-grid DC-to-AC PCEs, DC-to-DC converters, battery charger converters, and battery charge controllers. This document covers PCE that is connected to PV arrays that do not nominally exceed a maximum circuit voltage of 1 500 V DC.
This second edition cancels and replaces the first edition published in 2005. This edition includes the following significant technical changes with respect to the previous edition:
a. Title modified.
b. This edition focusses on the design qualification of power conversion electronics (PCE), and eliminates the clauses associated with qualification testing of other balance of system components.
c. While many clause titles remain the same as the first edition, substantial changes have been made.
d. Whereas the first edition establishes requirements for the design qualification of balance-of-system components used in terrestrial photovoltaic (PV) systems, this edition is limited to power conversion equipment.
e. The test protocols have been changed.
