The following schematic diagram (Figure 1) shows the patent-registered MELEC power electronic circuit. With this circuit it is possible to drive the output E1 and E2 in DC, Unipolar- and Bipolar Mode by switching Transistor T1, T2, T3 and T4. G1 and G2 are two floating DC-Power Sources which charge the Capacitors C1 and C2. MELEC‘s DC-Pulse Power Controller has no integrated DC-Source. The reason is the possibility to provide symmetric- and asymmetric bipolar voltage level on the outputs E1 and E2 by closing or opening S1 and S2. For symmetric bipolar output pulses one DC Source is needed and S1 and S2 has to be closed.
