Description

Technical Field

[0002] The function of the transformer-rectifier is to convert 115 / 220V, 400Hz AC power into 28V low-voltage DC power to power DC devices such as batteries. A typical transformer-rectifier is a combination of a transformer and a rectifier. The transformer reduces the AC voltage, and the rectifier converts the stepped-down AC power into DC power. Existing transformer-rectifiers often emit a lot of heat during operation, and a separate oil cooler is used for heat dissipation, but the heat dissipation effect is relatively poor, which will lead to a relatively low working efficiency of the transformer-rectifier, which is not conducive to people's use.
