Problems solved by technology

Therefore, noise is generated due to high-speed switching, resulting in radio frequency interference (RFI: radio frequency interference)
Additionally, existing LDC analog controllers require expensive filters to remove high-speed switching noise

Abstract

An apparatus for generating a switching signal for an analog controller includes: a voltage setting unit configured to set voltages Vref_high and Vref_low of a triangular wave; a period adjuster configured to adjust a period of the triangular wave; a triangular wave generator configured to generate the triangular wave at the period based on the voltages set by the voltage setting unit; and an AC component passing unit configured to pass an AC component of the triangular wave through a low voltage DC-DC converter (LDC) analog controller.

Description

technical field [0001] The present invention relates to an apparatus for generating a switching signal of an analog controller, and more particularly, to an apparatus for generating an alow DC-DC converter (LDC) used in a hybrid vehicle or an electric vehicle. A device for simulating switching signals in pulse width modulated controllers. Background technique [0002] Recently, research on hybrid vehicles or electric vehicles has been actively conducted in order to meet the current demand for improvement in fuel efficiency. The result is an increasing development of products that are more environmentally friendly. [0003] In general, a hybrid vehicle refers to a vehicle driven by effectively combining two different power sources. In particular, hybrid vehicles are generally driven by an engine (ie, an internal combustion engine) that obtains torque by burning fuel (ie, a fossil fuel such as gasoline) and an electric motor that obtains torque by battery power. [0004] A ...
