Abstract
The present disclosure relates to a digital control apparatus capable of high-speed sampling and a method therefor. According to the present disclosure, current or voltage sampling for controlling a PWM module of a power conversion device that is to be controlled is performed multiple times during a period of current or voltage, and thus it is possible to accurately control the digital control apparatus without considering a circuit or device delay of the digital control apparatus unlike the prior art.
Claims10
A digital control apparatus capable of high-speed sampling, comprising:
- a sampler configured to sample a current or voltage of a power converter;
- and
- a controller configured to control a pulse width modulation (PWM) module to adjust an output of the power converter based on the sampled current or voltage,
- wherein the sampler is configured to perform two or more samplings of the current or voltage during a single period of the current or voltage to be sampled.
A digital control method capable of high-speed sampling, comprising:
- sampling a current or voltage to adjust an output of a power converter;
- and
- controlling a pulse width modulation (PWM) module to adjust the output of the power converter based on the sampled current or voltage,
- wherein the sampling is configured to include performing two or more samplings of the current or voltage during a single period of the current or voltage to be sampled.
