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, coupled to the first power converter and 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, coupled to the first counter and 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;
- counting 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
- generating 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.
