The system also includes a first sensor configured to determine a first temperature of a fluid flowing from the heat exchange apparatus to the generator, a second sensor configured to determine a second temperature of the fluid flowing from the generator to the fluid supply and a controller configured to determine an operating limit temperature for the fluid based on the determined first and second temperatures. | 2012-10-04 |
20120249091 | POWER FACTOR CORRECTION BOOST CONVERTER AND FREQUENCY SWITCHING MODULATION METHOD THEREOF - The instant disclosure provides a Power Factor Correction (PFC) boost converter including a PFC converter unit and a control unit and a frequency switching modulation method thereof. The control unit outputs a pulse width modulation (PWM) signal to the PFC converter unit for adjusting an electronic power output to a voltage converter. As the output load of the PFC converter unit increases, the control unit increases the frequency of the PWM signal. Conversely, as the output load of the PFC converter unit decreases, the control unit reduces the frequency of the PWM signal. Consequently, the switching loss of the PFC converter unit is reduced. | 2012-10-04 |
