The proposed power supply for an amplifier with 100W V-MOSFET, as shown above, features separate supplies for different stages of operation. This includes a power stage, a control stage, a preamplifier supply, and a protection stage. Users can either suppress certain sections or add individual power supplies for each channel, leaving other channels idle if needed. Additionally, those who do not require the preamplifier or protection circuits can omit the corresponding components.
Output Voltages for Power Supply
+V1 = +60V, -V1 = -60V+V2 = +12V, -V2 = -12V
+V3 = +65V, -V3 = -65V
- Protection Circuit
- Power Amplifier 100W V-MOSFET
