High-Isolation DC-DCs Can Replace Two Converters In IGBT Systems
RECOM Power’s has designed a series of dc-dc converters with asymmetric outputs of +15 V and ‒9 V, suiting them for power insulated-gate bipolar transistor (IGBT) drivers. The asymmetric-output design effectively replaces the need for two converters. The devices come with input voltage of 5, 12, and 24 V dc, and offer up to 6.4 kVdc/1-sec. isolation. Operating temperature ranges from ‒40 to +90°C without derating. Efficiency elevates up to 85%. A variety of pin-outs and packages (single and dual in-line) meet requirements of various IGBT applications. All series members feature short-circuit protection, and are EN60950-1 certified. The converters will be available through Richardson RFPD, which also will offer full design support capabilities (technical expertise and design-in assistance).
