Embodiment Construction
[0050] The technical scheme that the present invention adopts is, a kind of constant power drive power supply based on ARM and multiplier, comprises following four parts:
[0051] The first part is the drive circuit, such as figure 1 As shown, it consists of a DDS (Direct Digital Synthesizer) chip 18, an integrated PWM (Pulse Width Modulation) wave control chip 6 (such as SG3525A) and an inverter amplifier circuit 5. The ARM microprocessor outputs two DA (Digital to Analog Convert ) signal controls the oscillation frequency and duty cycle of the integrated PWM wave control chip oscillator, and the ARM microprocessor controls the DDS chip to output a square wave of any frequency to the synchronous end of the integrated PWM wave control chip, precisely controlling the frequency of the output PWM wave, so as to realize the drive Synchronous and precise control of the frequency of the PWM square wave. The PWM square wave is driven to output to the inverter amplifier circuit 5, and...
