1.(i)Power converters in electric vehicles (EVs) are essential for converting and managing electrical power throughout the vehicle's systems. They play key roles in charging, motor control, and powering various onboard systems. DC-DC converters step down high-voltage DC from the battery to power lower-voltage components, while AC-DC converters handle charging from the grid.

In an electric vehicle (EV), power converters are crucial for converting and managing electrical power between the battery, various electrical components.

The external charging systems. Common applications include DC-DC converters for voltage regulation, inverters for AC power generation, and AC-DC converters for onboard charging. For an EV horn needing a DC voltage less than 10V, a DC-DC buck converter or a step-down converter would be suitable.

(iii)

In an electric vehicle (EV), power converters are essential for managing and converting electrical power to meet various needs. For a horn requiring DC and less than 10V, a DC-DC converter (likely a buck converter) is used. Other applications include:

1. Other low-voltage systems: DC-DC converters are used to power headlights, interior lights, wiper motors, and other low-voltage components.
