Abstract
A power consumption evaluation device and a power consumption evaluation method are provided. The power consumption evaluation device includes a power converter, a counter, and a controller. The power converter includes a power switch. The power switch performs a switching operation according to a control signal, so that the power converter supplies power to a corresponding load among at least one load. The counter counts one of a positive pulse and a negative pulse of the control signal during a measurement period to obtain a count value. The controller generates an evaluation result of the corresponding load according to the count value.
Claims20
A power consumption evaluation device, configured to evaluate a power consumption of at least one load, the power consumption evaluation device comprising:
- a first power converter, comprising a first power switch, wherein the first power switch performs a first switching operation according to a first control signal, so that the first power converter supplies power to a first load among the at least one load;
- a first counter, directly coupled to the first power converter and configured to receive the first control signal directly outputted from the first power converter, wherein the first counter is further configured to count one of a positive pulse and a negative pulse of the first control signal during a measurement period to obtain a first count value;
- and
- a controller, directly coupled to the first counter and configured to receive the first count value directly outputted from the first counter, wherein the controller is further configured to generate a first evaluation result according to the first count value, wherein the first evaluation result is associated with a first power consumption of the first load during the measurement period, wherein the first power consumption is proportional to the first count value.
A power consumption evaluation method, configured to evaluate a power consumption of at least one load, the power consumption evaluating method comprising:
- connecting a first power converter to a first load among the at least one load;
- performing a first switching operation by a first power switch of the first power converter according to a first control signal, so that the first power converter supplies power to the first load;
- using a first counter to count one of a positive pulse and a negative pulse of the first control signal during a measurement period to obtain a first count value, wherein the first counter is directly coupled to the first power converter, and the first counter is configured to receive the first control signal directly outputted from the first power converter;
- and
- using a controller to generate a first evaluation result according to the first count value, wherein the controller is directly coupled to the first counter, and the controller is configured to receive the first count value directly outputted from the first counter, wherein the first evaluation result is associated with a first power consumption of the first load during the measurement period, wherein the first power consumption is proportional to the first count value.
