Some time ago, I reverse-engineered a low-cost inverter made by Vector Mfg. (now Black & Decker). It uses a classic 2-BJT astable multivibrator (AMV) but with a circuit design twist, as shown below.
Fig 1. The voltage downconverter for high-power-density lithium-polymer batteries enables them to replace older battery technologies in applications that otherwise could not employ their higher ...
The figure shows a 555 timer used as an astable multivibrator. Determine the values t1, t2, frequency and duty cycle of the output waveform. When a 555 timer operates as an astable multivibrator, the ...
