Conventional inverter output stages e.g. used in high
dynamic power inverters for servo applications or
switching mode amplifiers mostly use the well known
halve bridge topology (c.f. Fig. 1). Some modern
solutions deal with the advantage of the usage of
additional (linear or switching mode) assistant
amplifier stages, connected in series or parallel and
operating at lower voltage levels, leading to higher
system speed for improving the small signal bandwidth
[1..4]. The proposed solution uses a design of
cascaded power stages leading to optimised results
for signal bandwidth, output signal quality and power
system losses. By selection of each inverters
operating conditions the designer can fully affect the
system behaviour leading to an optimal fitted solution
in all respects.
Keywords: Inverter, Solar, PWM, switching losses
