Many photographers own more than one electronic flash system. In the studio, a heavy, high-output power generator often seems best, especially when using softboxes and other light modifiers.

Aiming at the problem of bus voltage control in DC microgrid, a dynamic compensation control strategy based on a residual generator is designed to complete the voltage compensation of DC-DC converter.

Astoundingly it worked, and with the output voltage adjusted to just over 150V the pulse generator started oscillating as it should.

If the cumulative gate-output duty cycle is 50% and swings rail-to-rail, the A1 voltage follower will output V CC /2, because C3 will charge and discharge to this average voltage.
