Patent ID: 8416583

Claim:
An energy output control method comprising: installing a controller controlling a switch device of an energy output circuit; implementing the controller to calculate a required output energy waveform according to an output energy requested by an electric device or a pre-set output energy level decided by an operator; implementing the controller to design an expected energy output waveform for the controller in accordance with the required output energy waveform; and implementing the controller to send a command in accordance with the expected energy output waveform to control the switch device, to control an on/off time of a primary of an ordinary low-frequency transformer via the switch device; implementing the controller to receive a feedback signal generated from an output of the ordinary low-frequency transformer and modulate the expected energy output waveform, wherein the controller calculates a pulse width, a turn-off time and a switch control timing according to the following method: a.) defining an End Time (te) which is a finish time of a first pulse and is a Present Time (tw) of the first pulse, and is also a Start Time (to) of a second pulse that is previous to the first pulse, and a time serial number (n) is 0; b.) calculating a Turn-On Time(tn) according to a voltage (v) of the Present Time (tw); wherein when the voltage (v) equals a maximum voltage (Vmax), a Start Time (to) of the first pulse equals a start time of a horizontal section of the expected energy output waveform, the Turn-On Time (tn) equals the Present Time (tw) minus the Start Time (to) of the first pulse and wherein when the voltage (v) is less than the maximum voltage (Vmax), the Turn-On Time (tn) equals a Minimum Turn-On-Time (t), the-Start Time (to) of the first pulse equals the Present Time (tw) minus the Minimum Turn-On Time (t) minus a minimum Demagnetized Time (Tc); c.) incrementing the time serial number (n) by 1 while the Present Time (tw) equals the Start Time (to) of the second pulse that is previous to first pulse; and d.) repeating the steps b.) and c.) until the Present Time (tw) equals 0, that is a start time of the expected energy output waveform.
