Abstract
Disclosed are an LDC control apparatus for preventing an LDC from being overheated, and a method of operating the same. The LDC control apparatus includes a comparator configured to compare a heat release temperature of an LDC with a predetermined criterion temperature, an adjustor configured to adjust a predetermined criterion current value according to a result of the comparison of temperature, and a controller configured to compare the adjusted criterion current value with an output current value being output from the LDC, and control the LDC by converting a control mode of the LDC according to a result of the comparison of current.
Claims12
A low voltage DC-DC converter (LDC) control apparatus comprising:
- a comparator configured to compare a heat release temperature of an LDC with a predetermined criterion temperature;
- an adjustor configured to adjust a predetermined criterion current value according to a result of the comparison of temperature;
- and
- a controller configured to compare the adjusted criterion current value with an output current value being output from the LDC, and control the LDC by converting a control mode of the LDC according to a result of the comparison of current.
A method of preventing overheat of a low voltage DC-DC converter (LDC) by using an LDC control apparatus, the method comprising:
- comparing a heat release temperature of the LDC with a predetermined criterion temperature;
- adjusting a predetermined criterion current value according to a result of the comparison of temperature;
- comparing the adjusted criterion current value with an output current value being output from the LDC;
- and
- controlling the LDC by converting a control mode of the LDC according to a result of the comparison of current.
