Charging apparatus
First Claim
1. A charging apparatus providing a target electric parameter value and supplying electric power to a load, the charging apparatus comprising:
- a power requirement unit and a power supply unit;
wherein the power requirement unit comprises;
a first sensing module for detecting an electric parameter value of the load, anda first control module for receiving the electric parameter value;
wherein the power supply unit comprises;
a second control module receiving the electric parameter value and providing a first frequency, a second frequency and a frequency difference; and
a power switching module;
wherein the second control module is configured to calculate an accumulated difference value based on the electric parameter value and the target electric parameter value, the second control module is configured to switch the power switching module at the first frequency with times of a first count and to switch the power switching module at the second frequency with times of a second count;
wherein when the accumulated difference value is larger than an adjustment upper bound, the second control module is configured to use the second frequency as a new first frequency and to use the second frequency subtracting the frequency difference as a new second frequency;
when the accumulated difference value is smaller than an adjustment lower bound, the second control module is configured to use the first frequency as the new second frequency and to use the first frequency plus the frequency difference as the new first frequency;
whereby the electric parameter value is adjusted to the target electric parameter value.

Abstract
A charging apparatus includes a power requirement unit and a power supply unit. The power requirement unit has a first sensing module and a first control module. The first sensing module senses an electric parameter value of a load. The first control module receives the electric parameter value. The power supply unit has a second control module and a power switching module. The second control module receives the electric parameter value to switch the power switching module according to an accumulated difference value produced by the electric parameter value and a target electric parameter value, thereby controlling the electric parameter value to be equal to the target electric parameter value.
