• the primary power processor 146 drives the inverter 148 to transmit the maximum power.
• the maximum power is available immediately during the switch-on process, whereby start-up delays, for example motor drives, are avoided.
• the maximum secondary power is generated by increasing the primary voltage to the maximum value and the maximum pulse width adjuster. Voltage levels that are too high for the respective consumer on the secondary side are blocked by the voltage limiting device 158.
• the primary power processor 146 uses the current measuring device 157 to determine the power by reducing the primary voltage and / or the pulse width until, after the transfer characteristic stored in the data memory, the secondary power required for the consumer must be present.
