As shown in FIGS. 11 and 16, the DC circuit includes an input circuit, a DC-DC circuit, an output circuit, an indication circuit, a PWM modulation circuit, a voltage sampling circuit, and a current sampling circuit.

The input circuit is a ripple suppression circuit that filters the ripple AC voltage in the input; the DC-DC circuit is a DC-to-DC circuit controlled by a P-modulation circuit, and the output circuit is also a ripple suppression circuit. The output voltage ripple coefficient is extremely small; the P-modulation circuit is a pulse width controller that comprehensively analyzes the signals output from the voltage sampling circuit and the current sampling circuit to control the conduction of the electronic switches in the DC-DC circuit.

At this time, the voltage sampling circuit will output the voltage at the output terminal. Sampling to the P-modulation circuit, the P-modulation circuit will adjust the on-pulse width of the electronic switch in the DC-DC circuit to compensate for the decrease in the output voltage; when the current sampling circuit samples the load current beyond the specified value, it will output a signal to Pray The circuit, the P-modulation circuit will adjust the on-pulse width of the electronic switch in the DC-DC circuit to reduce the output current value and control the current within the design value; thus the entire circuit can serve the purpose of constant power output.
