The invention discloses a pulsed power supply and electrical equipment. The pulsed power supply comprises a master controller, a voltage regulating circuit, a frequency regulating circuit and a pulsedpower supply drive circuit, wherein two control signal output ends of the master controller are connected with a controlled end of the voltage regulating circuit and the controlled end of the frequency regulating circuit separately; an input end of the voltage regulating circuit is used for being connected to a DC power supply; an output end of the voltage regulating circuit is connected with theinput end of the pulsed power supply drive circuit; the output end of the frequency regulating circuit is connected with the controlled end of the pulsed power supply drive circuit, wherein the master controller controls the voltage regulating circuit to convert the connected DC power supply into power supply voltage with a corresponding voltage value and to output the power supply voltage when receiving a power supply regulating signal, and controls the frequency regulating circuit to generate a drive signal of a corresponding frequency to drive the pulsed power supply drive circuit to workand to output the power supply voltage with the corresponding voltage value. According to the pulsed power supply, the problem that simultaneous adjustment of the frequency and amplitude cannot be easily achieved in an existing pulsed power supply is solved.
Description
technical field [0001] The invention relates to the technical field of electronic circuits, in particular to a pulse power supply and electrical equipment. Background technique [0002] In electrical equipment such as lasers, infrared or ultrasonic instruments, most of them require output of nanosecond or even picosecond pulse power. For example, the semiconductor laser power supply needs a pulse width of 100nS, or even 10nS pulse, and the frequency needs to meet the frequency conversion application of 10-20MHz at the same time, and the power supply voltage is adjustable between 5-9V. However, it is difficult for the existing pulse power supply to satisfy both the adjustable frequency and the amplitude at the same time. Contents of the invention [0003] The main purpose of the present invention is to propose a pulse power supply and electrical equipment, aiming at solving the problem that the existing pulse power supply is difficult to realize simultaneous adjustment of ...
