Scope
Scope: This document specifies the technical requirements, test methods, and inspection rules for modular high-frequency isolation step-up photovoltaic DC converters (hereinafter referred to as "converters"). This document applies to newly manufactured converters that meet the following conditions: a) The maximum open-circuit voltage of the photovoltaic string connected to the junction box is less than or equal to 1,500V; b) The DC output voltage is greater than or equal to ±3kV and less than or equal to ±35kV; c) The operating frequency is greater than or equal to 1kHz, and the voltage conversion and electrical isolation are achieved by an isolation transformer; d) Energy flows unidirectionally from the photovoltaic array to the DC distribution network.
