WebFeb 23, 2015 · A simple blocking oscillator circuit can be used to step up voltage using properties of coil inductance ( V = L di/dt ). Such a circuit is shown in Figure 1 , which is more commonly called a Joule thief. Figure … A blocking oscillator (sometimes called a pulse oscillator) is a simple configuration of discrete electronic components which can produce a free-running signal, requiring only a resistor, a transformer, and one amplifying element such as a transistor or vacuum tube. The name is derived from the fact that the amplifying element is cut-off or "blocked" for most of the duty cycle, pr…
