POWER SUPPLY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240266849 titled 'POWER SUPPLY DEVICE

Simplified Explanation

The patent application describes a reverse connection protection relay for a power supply device that prevents current flow from the power converter side to the battery side when the relay is turned off. It includes a booster circuit for overboosting, a precharge circuit for applying boosted voltage, and a monitoring circuit for detecting abnormalities in the relay.

The protection relay is parallel connected with a diode to allow current flow from the battery side to the power converter side.
A booster circuit temporarily raises the target voltage above normal levels during an overboost process.
A precharge circuit boosts the voltage applied to an electrode on the high potential side of the input capacitor.
A monitoring circuit detects abnormalities in the protection relay based on the post-relay voltage on the inverter side.

Original Abstract Submitted

a reverse connection protection relay of a power supply device is provided in a power supply line between a battery and an input capacitor and is parallel connected with a diode that allows current flow from a battery side to a power converter side, and interrupts the current flow from the power converter side to the battery side when the protection relay is turned off. at a time of initial check, a booster circuit performs an overboost process in which a target voltage is temporarily raised above a value during normal operation. a precharge circuit applies a boosted voltage to an electrode on a high potential side of the input capacitor. a monitoring circuit detects an abnormal due to being stuck in an on state or in an off state of the protection relay according to a post-relay voltage that is a voltage on the inverter side of the protection relay.
