Subject: PZT driver board verification 

[ Yuki, Gautam ]

I fixed the input terminal that had been off, and made sure PZT driver board performs as we expect. 

At first I ran a simulation of the PZT driver circuit using LTspice (Attached #1 and #2). It shows that when the bias is 30V the driver performs well only with high input volatage (bigger than 3V). Then I measured the performance as following way:

  1. Applied +-15V to the board with an expansion card and 31.8V to the high voltage port which is the maximum voltage of PS280 DC power supplier C10013.
  2. Terminated input and connectd input bias to GND, then set offset to -10.4V. This value is refered as elog:40m/8832.
  3. Injected DC signal into input port using a function generator.
  4. Measured voltage at the OUT port and MON port.

The result of this is attached #3 and #4. It is consistent with simulated one. All ports performed well.

  • V(M1_PIT_OUT) = -4.86 *Vin +49.3 [V]
  • V(M1_YAW_OUT) = -4.86 *Vin +49.2 [V]
  • V(M2_PIT_OUT) = -4.85 *Vin +49.4 [V]
  • V(M2_YAW_OUT) = -4.86 *Vin +49.1 [V]
  • V(M1_PIT_MON) = -0.333 *Vin +3.40 [V]
  • V(M1_YAW_MON) = -0.333 *Vin +3.40 [V]
  • V(M2_PIT_MON) = -0.333 *Vin +3.40 [V]
  • V(M2_YAW_MON) = -0.333 *Vin +3.40 [V]

The high voltage points (100V DC) remain to be tested.
