RV Converter: How It Works

For anyone who’s ever spent time in an RV, you know how important it is to have a reliable power source. When you’re on the road, you need to be able to power all of the electronics, lights and appliances, and you need to be able to do it without worrying about your batteries dying or your generator running out of gas.

That’s where RV converters come in. An RV converter is a piece of equipment that converts 120-volt AC power (like you would find in a house) into 12-volt DC power (like you would find in a car). This type of power is used to power your RV’s appliances, lights, and electronics, and it’s what keeps your battery charged when you’re plugged into shore power.

Understanding the Components of an RV Converter

At its most basic level, an RV converter is made up of two main components: a transformer and a rectifier. The transformer is responsible for converting the 120-volt AC power into a lower voltage that can be used to charge your RV battery, while the rectifier converts the AC power into DC power. Additionally, most RV converters also include a built-in battery charger, which allows you to charge your battery directly from shore power. Some newer RV converters even include a built-in inverter, which allows you to convert DC power back into AC power, giving you the best of both worlds.

How an RV Converter Works

When you plug your RV into shore power, the electrical system in your RV automatically switches over to the converter, which is responsible for supplying power to all of your appliances, lights, and electronics while also charging your battery. As mentioned, the transformer steps down the voltage from 120 volts to a lower voltage that can be used to charge your battery, while the rectifier converts the AC power into DC power. As you use power in your RV, the converter continues to supply DC power to your electrical system. If you’re plugged into shore power and your battery is fully charged, the converter will supply all of the power you need. If your battery starts to run low, the converter will automatically switch to charging mode, providing power to both your electrical system and your battery.
