Sine-wave step-up converter uses Class E concept


Posted on Apr 20, 2012

The circuit requires only one power-switching device, and you can use an analog or a digital signal to drive the switching device. The circuit also requires only a few components: a diode, a switching transistor or a MOSFET, an inductor or a transformer, and a capacitor. Further, the design`s circuit losses are low, and the switching device experiences minimal stress during operation. Figure 1 shows the basic circuit, and Figure 2 illustrates waveforms within the circuit.
