My 2005 built radio controlled Z5660M Nixie clock used a simple HV PS with back to back transformers. I used a Galleon MSF receiver and built the clock exclusively with logic ICs! It also had PWM dimming via a LM324N and a LDR. The radio clock worked fine with minimal distance needed between the ferrite antenna and the PCB circuitry.
I'm looking to redesign this clock (SMD / Micro / 12Vdc Supply) and would like to use a small SMPS for the HV. I realise using a SMPS is going to make things more "noisy". I've done preliminary tests with a couple of SMPS HV modules: the KOSBO and TES1363. With the KOSBO unit the radio signal is stable when the antenna is positioned more than 30cm from the SMPS. With the TES1363 it's about 1m. Both were driving 6x Z5660M directly, 180V / 20mA total. My Questions: Am I just fighting a lost cause trying to see if I can house the MSF receiver / antenna with the clock case (or very close) as opposed to having a separate housing and long connecting cable? Is there a small quiet HV SMPS design? Will mechanical shielding be of any help with a SMPSs above? What is the quietest HV PS design of any description?
