Embodiment Construction
[0031] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0032] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0033] The present invention provides a DSP2812-based multi-channel superimposed high-frequency high-voltage power supply, which adopts a multi-stage series mode to output high voltage such as figure 1 As shown, using the VVVF (Variable Voltage Variable Frequency) modulation method, the high-frequency and high-voltage multi-channel power supply is a group of four power supplies. According to the technical requirements, the voltages of each channel are related to each other in frequency, amplitude and phase, so it can be expressed by the following formula :
[0034] V 1 =ksin(wt)+A 1
[0035] V 2 =ksin(wt+Q 2 )+A 2
